Blood smeared across the floors and splattered up the walls, these are the horrifying photos from inside the child asylum centre where a female Swedish social worker was murdered in ‘a frenzied attack’.

Alexandra Mezher, 22, bled to death after being stabbed three times in the back with an Ikea kitchen knife and once in thigh by one the young migrants she was caring for.

The grisly pictures show that Miss Mezher appeared to have put up a fight against her killer.

Bloodbath: This is the kitchen where 22-year-old Alexandra Mezher was attacked, allegedly by Youssaf Khaliif Nuur, who said he was 15

Escape: Miss Mehzer then tried to crawl away from her attacker, making her way along the corridor, leaving a trail of blood

Deadly: Police have said the severity of her injuries were such she would have needed medical attention within minutes to survive

Defence: Other young migrants, who heard her screams, tried to intervene - the first one was beaten back, but another overpowered Nuur

Begging for her life: Witnesses say she yelled 'No, no, no Youssaf’ at least 10 times as he allegedly carried out the frenzied attack

Charged: Nuur, who says he is from an Ethiopian village, pictured after his arrest, claims he cannot remember anything of the attack itself

The trail of blood reveals for the first time how she tried to escape from the vicious attack, managing to crawl from the kitchen where she was stabbed with such force her artery was severed.

The psychology graduate, originally from Lebanon, then pulled herself along the corridor, seeking safety in a bedroom.

It was here – lying on the floor in amongst the white sheets stained red by her blood – that she lost her fight for life.

'The young man has shown extreme ruthlessness and harshness which caused the death of Alexandra Mezhers,' prosecutor Linda Wiking noted.

Detectives arrived at the centre for unaccompanied minor refugees in Mölndal, a suburb of Gotherburg, to find this scene of carnage with a pot plant kicked over on the stairwell.

Asylum seeker Youssaf Khaliif Nuur, from Ethiopia, who claimed to be just 15 to win himself a spot in the home, is charged with her murder.

Prosecutors, who released the photographs as part of a report into the shock killing, can now conclusively say he is at least 21, if not older, meaning he should not have been at the centre, which was for teenagers aged 14 to 17.

The report also reveals witnesses interviewed by police told how Miss Mezher begged for her life, and was heard to scream ‘No, no, no Youssaf’ at least 10 times as he stabbed her.

Hiding place: Miss Mezher spent her final moments in this room, where she bled to death after her artery was severed

Safety: This is the bedroom where Miss Mezher ended up, after pulling herself to safety down the hallway on January 25

Desperation: Her bloody fingerprints appear running up the door, reaching for the door handle of room five

Fatal: She had been stabbed with such force, the artery in her leg had been severed - causing her catastrophic loss of blood

Vicious: Miss Mezher also had stab wounds to her back and to her hands, suggesting she had tried to defend herself from the onslaught

Tricked: Ethiopian asylum seeker Nuur claimed to be just 15 to win himself a spot in the young migrants home in Gothenburg

Truth: It has now been proved he is at least 21, after it was immediately suspected that Nuur was ling

Lead up: Miss Mezher already knew a knife had gone missing from the kitchen before she started her shift. Pictured: The murder weapon

One of the other residents tried desperately to help the young woman, but was attacked himself before more boys arrived to help.

‘Just a few seconds later more boys came in to the kitchen and overpowered the man with the knife,’ the report continued.

‘Alexandra then manages to get away from the scene. A few minutes later they make a distress call to the police.’

But Miss Mezher, who had worked at the centre for just four months, bled to death before help arrived, in the sparsely furnished room.

She would have needed treatment within minutes if she were to have any chance of survival, the report says.

Arrested: The report also included pictures of Nuur wearing a blood-spattered t-shirt at the police station after the killing

Mystery: Nuur still refuses to say what his true age is, and his story about where he comes from in Ethiopia is muddled

Decision: Nuur has now been charged as an adult, and it is suggested that he will be deported if found guilty

Horrifyingly, it also reveals Miss Mezher knew she was in danger the day she went to work to cover the night shift by herself.

Her mother Chiméne Mezher, 42, told police: ‘She got a call from her job saying that someone had taken a knife. She sat on the sofa, but got up and went into the bedroom and talked.

‘I do not think she wanted me to know she did not want me to worry worried. It was the 24th, she sat and calmly painted her nails. She knew how she would handle it.’

Mrs Mezher, 42, a mother-of-four, who moved from Lebanon 25 years ago, said previously: ‘Alexandra knew how to handle children including violent ones.

'But those she was working with were big powerful guys - she could see it in their eyes and their bodies.

'A few were maybe under 18, but the rest were older, maybe 23 or 24.'

Witnesses told detectives the atmosphere was ‘calm and normal’ on the night of the killing – and there was no tension between Nuur and Miss Mezher.

But at 8am on January 25 she was set upon by her killer in a prolonged and brutal attack.

Nuur, who faces trial for her murder, claims he has no memory of the killing.

His inability to tell police what happened during those crucial minutes has left Miss Mezher's parents even more distressed.

Hans Gaestadius, the lawyer representing the Mezher family, told reporters: ‘A mother and father who lose a young daughter like that are of course devastated.

‘What upsets my clients most is that they have not gotten the answers they need. The killer has not said why he did it.

‘Instead he say that he can not remember anything. He has a gap in his story just when he committed his crime.

‘The strange thing is that he remembers everything before and after the attack. We believe that this gap is deliberate and strongly question if he is telling the truth.’

A source had previously revealed to MailOnline that Nuur - who was refused housing elsewhere due to concerns over his mental health - may have suffered some sort of a breakdown ahead of the killing.

'The knifeman may have had some kind of breakdown. He may have suffered some trauma previously in his life,' the source said, adding that Nuur had complained of feeling 'unwell' the night before and had not slept at all in the hours before the alleged attack.

He was heard pacing around his bedroom for most of the night before the attack.

A scuffle broke out at 8am and Miss Mezher reportedly tried to break it up.

A Gothenburg Police source told MailOnline: ‘This lady tried to separate them and told him to stop but he stabbed her. The suspect had been up all night. He had said he was not feeling well the night before.’

Home: The asylum centre catered for about 10 teenage boys who had arrived in Sweden unaccompanied

Lies: Miss Mezher, who had worked there since September 2015, had told her mother many of the 'boys' were men

The horrific murder of Miss Mezher came just more than a year after a therapist at the housing centre in Molndal warned that due to lack of staff, ‘something serious will happen here’.

HVB Living Nordic, which runs the centre, is now under investigation by Sweden’s Work Environment Administration to see if they broke work environment laws for allowing Miss Mezher to work on her own with 10 teenage boys.

HVB Living Nordic is a private company paid by the local authority to provide housing and care for unaccompanied minors, which has been operating since late 2013.

In 2014, Molndal received £22.6million to provide housing for unaccompanied minors – the most state funding per capita than any town or city in Sweden.

That same year, HVB Living Nordic reported a profit margin of 21.9 per cent.

Questions: HVB Living Nordic is now under investigation by Sweden’s Work Environment Administration to see if they broke work environment laws for allowing Miss Mezher to work on her own with 10 teenage boys the night she died

Stress: Sweden has seen a huge influx of migrants in the last year, adding to tensions in the country between locals and refugees

HVB’s chief executive is Patrick Sjögren, 46, former CEO of 5050Poker, a gambling website which filed for bankruptcy in 2012 after it emerged that the company had used players' money to cover losses.

The company, HVB Living Nordic, had asked the local authorities for compensation to care for Nuur, but the extra staff promised had reportedly not started yet at the time of the attack.

This despite the fact that Nuur had lived at the centre in Molndal, home to ten migrants, for a month before the murder. Some 4,000 arrived without their parents in the past year alone at the suburb, which has a population of just 60,000.
