A teen gang member released from jail just two years after killing another youth in Croydon has described himself "a money makin' machine soon 2 be bak on road".

In a series of remorseless rants on his social networking website, the young thug - who was part of a gang who killed Stefan Persaud - talks about his joy at being released from prison early.

It is thought the website was set up during the teen's stay in jail but Prison Service bosses have insisted it must have been done by a friend or family member on the outside.

The 17-year-old, who cannot be named for legal reasons, was caged last year after being convicted of the manslaughter of 16-year-old Stefan.

Three other youths, including cousins David and Sean Ramsey and a third, Tyrone Bailey, were jailed for 15 years for murder.

Stefan was battered to death with bricks and hammers by the four youths, who were members of a gang called Til Death'.

They chased Stefan into a front garden in South Norwood while chanting their "battle cry".

Stefan, who was due to do his GCSEs at Stanley Technical College, was then knocked to the ground and had paving slabs dropped on his head as he lay unconscious.

He was taken to hospital and kept alive for more than two weeks before dying from severe head injuries and more than 30 separate wounds.

But there is clearly no remorse from this teenager, who was released at the end of September.

On his profile, which was created after he was remanded to prison in October 2005, he writes: "Im a money makin machine soon 2 be bak on road but in jail now 3 me and ma niggas."

He also writes on his profile that he is happiest when he is making money and his home town is "South Norwood Arena Slums".

This was not the first time time Stefan's killers had posted sick messages relating to the case.

Shortly after his death they later claimed on an internet site dedicated to Stefan's memory their victim "deserved it" and needed to be taught a lesson.

One message read: "Poetz (Stefan's nickname) only had himself to blame because he's a di*khead.'"

The killers were notorious for terrorising the South Norwood area, targeting schoolboys for their jewellery and mobile phones.

Several were banned from hanging around the gates of Edenham Secondary School in Shirley, Croydon, after the headmaster heard they were intimidating pupils.

A spokesman for the Prison Service said: "Prisoners are not allowed any internet access at all apart from online learning courses.

"It is almost impossible that he has done this himself but it is common for these sorts of pages to be updated on behalf of the prisoners by friends and family."
