A witness who helped a cyclist viciously attacked by a group of teenagers is being sought by police.

Filipe Nunes David, a 39-year-old Portuguese national, was left with serious head injuries including a fractured skull in the attack.

Detectives investigating the attack on the Ewell cyclist are appealing for the driver of a black car, who spotted Mr Nunes David and stopped to help, to contact them.

The driver is described as a white woman aged around 50, with a dark bob-style haircut, wearing a long floral skirt and a black top. She gave Mr Nunes David a blanket and waited with him until paramedics arrived before continuing with her journey.

Her identity is still unknown and police are keen to speak to her as part of the investigation into the savage beating.

Mr Nunes David was cycling along Cox Lane in Ewell at around 9.30pm on August 18 when he was attacked by a group of men sustaining serious head injuries. His attackers then ran away leaving him bleeding on the ground.

Mr Nunes David was taken to hospital in critical condition and put on life-support. His condition has since stabilised but his injuries are extremely serious.

Detective Inspector Jeff Brooks, of Surrey Police, said: “We are continuing to piece together all the events of that night and we need to speak to everyone who was on Cox Lane around the time of the attack.

“In particular we would like to speak to the driver of this car who saw Mr David in distress shortly afterwards. There is no need for you to be concerned but we do need to speak to you so we can build up a complete picture of events.

“If you were the driver or you know who they are please get in touch with police as soon as possible.”

Brett Carslake, aged 20, and two 16-year-old boys, who cannot be named, all from Ewell, have been charged with GBH with intent.

They were remanded in custody to appear at Guildford Crown Court on November 6.

Two other teenagers, an 18-year-old and a 16-year-old, were released on police bail pending further enquires.
