A teenage girl who was scene in a car crash which killed her friend says she is considering suicide, according to comments posted on a website in her name.

The Bebo social networking site says Chelsea Barnes may end her life because it has been turned upside down by the crash.

Chelsea was one of five youngsters in a red Mazda which smashed into a garden wall in Wilson Avenue, Whitehawk, Brighton, on February 8.

The car was seen driving erratically and police signalled for it pull over before pursuing it. But the driver did not stop and the car crashed.

Matt Sadler, 17, of Whitehawk Way, Brighton, died immediately. The other four occupants of the vehicle were taken to the Royal Sussex County Hospital in Brighton.

The website reads: "RIP matty i hope your okay up there watching over those who need you right now xx "Well before this crash my life couldnt have been better, now i hate my life im woundering wether to join u up ther m8.

"RIP matty, i hope yu dont think of me that way, do you want michael to go to prison."

Since the crash, Matt's friends and family have posted comments on the website pleading with Chelsea to tell the police everything she knows about the accident.

Chelsea was the girlfriend of Michael Morden, of Haybourne Road, Brighton, who was arrested on suspicion of causing Matt's death by dangerous driving.

He has not been charged and has been released on police bail until June 13.

One comment posted on the web page reads: "How bout telling the people that really matter n the people that can stop more hurt and anguish from happening."

After the crash, Chelsea and Amy Fitzsimmons, who were both 15 at the time of the incident, and Michael Morden, 16, were released from hospital with minor injuries.

Simon Piercy, 16, was treated for injuries. Friends say he has a broken leg and ribs, bleeding on the brain and kidney and liver damage but is improving.

Bilal Boulaich, of Haybourne Road in Whitehawk, escaped injury after getting out of the front seat of the car in Meadowview, Brighton.

Matt's funeral took place on March 20 at Downs Crematorium in Bear Road, Brighton.

Police officers stood guard to prevent people from attending who had been banned by his family.

In late February police were called after Matt's mum, Marie Sadler, complained of being harassed at her Whitehawk home.

Michael Morden was spoken to by officers, who told him to give Mrs Sadler time to grieve for her son.
