A suspect in case of Ilyas Habibi who was stabbed to death in Sutton was reportedly able to flee the country when officers failed to alert border and immigration due to an “error with the computers”.

Ilyas Habibi was attacked while he was travelling home from college after leaving Sutton train station on December 5.

Minutes after he came out of the station, he was involved in an argument with a suspect who then fled the scene.

On December 11, officers found he had left the country from London Gatwick Airport two days before.

Ilyas’ brother, Mr Habibi, has since spoken to The Independent, claiming that he was told by the police that there had been an “error with the computers”, which had allowed him to escape.

Speaking to The Independent, Mr Habibi said: “I’m only trying to think about who killed my brother.

“The police don’t even get in contact, someone was murdered and they don’t care.

“We want to know what steps they’re taking but they don’t tell us, I’m honestly shocked.

“How could he escape after four days?

“He murdered my brother outside a train station and next to a police station.

“They told us there had been an error with the computers and that’s why border and immigration weren’t told.

“They knew who it was two days before he fled the country – they went to his house but he had already gone.”

The Independent said that the Metropolitan Police refused to respond to claims the suspect was able to flee the country due to a computer error.

Mr Habibi said that the alleged killer also recently contacted him, joking and laughing about how he left Ilyas “choking on his blood.”

A separate man, 19, was arrested in December on suspicion of assisting an offender but was released on bail.

Mr Habibi has since claimed that his family had been provided with no update on the investigation.

Your Local Guardian previously spoke to Mr Habibi who told of the moment he found out about the death of Ilyas through doorbell footage of the police telling his parents the news.

Mr Habibi was proud to watch Ilyas grow over the years before his life was taken away from him.

He said: “I was at work at the time and Ilyas usually comes to where I work after he finished college.

“On that day my mum called me and asked, ‘Is Ilyas with you, his phone is off?’

“So, I tried to call him, but his phone was off and then dad called me to say: ‘Ilyas is not picking up’

“We decided to wait for around 30 minutes before deciding to call the police.

“I got a notification on my phone from the doorbell camera, so I thought Ilyas was home, so I decided to look at the footage to see what Ilyas is doing.

“I saw two officers standing outside and my dad answered the door and the officers said, are you Ilyas’ mum and dad?

“They said: Yes. And the officers responded: “Ilyas has been stabbed and his dead.”

After hearing the devastating news, Mr Habibi started screaming where he eventually fainted at work.

He was dropped off home by one of the staff members where he saw his mum and dad screaming.

Mr Habibi added: “That moment right there has traumatised me for the rest of my life and I’ll never be able to forget it.”

A day before his death, Ilyas visited his brother at his workplace asking Mr Habibi to book his driving theory test.

Mr Habibi explained: “This was the last time I spoke with Ilyas. He was happy, came to the shop and asked me to book his test.

“I asked him, Ilyas, ‘Are you sure you’re ready?. He replied: “Yes bro.”

“So, I booked him his test for his for the Wednesday at 9am.”

Mr Habibi’s mum faints “five to six times a day” and spends her time crying in Ilyas’ room following his death.

Mr Habibi said: “The house is so empty. Ilyas is room is next to mine. I haven’t slept.

“My heart is just aching. If I close my eyes, I see Ilyas in front of me.”

Mr Habibi was shocked that no arrests had yet been made a week after Ilyas’ death as there was “loads of cameras and witnesses” at the scene.

He said: “Ilyas was not stabbed in an alleyway, it was outside a train station where there’s loads of cameras and witnesses.

“So how have there been no arrests made yet? We keep in touch with the police a lot but there’s never a new update.

“We need to know every step the police is taking. It will calm my mum to know that her son’s killer is being looked for.

“It doesn’t help my mum knowing that his son’s killer is sleeping in nice warm house, eating nice food and walking around like nothings happened.

“I just hope justice is served for my brother. I really do.”
