The brother of a 16-year-old boy shot dead in an execution-style revenge murder seven years ago has urged people to help police catch his killers.

Yasser Hussain Nazir died instantly when he was shot twice in the head as he sat in a car in the forecourt of a filling station in Haworth Road, Chellow Heights, Bradford, on September 5, 2001.

An inquest into his death yesterday heard that, although about a dozen people had been questioned by detectives, people were still too frightened to reveal the identities of the murderers.

Speaking after Bradford Coroner Roger Whittaker recorded a verdict of unlawful killing, Yasser’s brother, Mohammed Saddique, urged people to be brave enough to come forward.

“If anyone has any information we would be very grateful if they would come forward and assist the police, something might just produce helpful results.

“To come here and not resolve the matter and for it to be left open is very hard for us.

“We haven’t really coped since my brother’s murder, life has not been the same. We grieve every day.”

He added: “What I would also say is that it could be one of your family next time.

“We hope that no-one else has to go through this but if we do not get these people behind bars these things will only keep on happening.”

The inquest was told that on the day of the murder Yasser, of Chatsworth Street, Keighley, had been illegally driving a white Vauxhall Astra with two friends after attending a police station in Bradford.

In Haworth Road, a red Mercedes-Benz car in front of them, the driver of which the inquest was told was known to the three, began swerving across the road.

Yasser pulled into the filling station forecourt and a green Honda Accord pulled up alongside. A passenger in the Honda then shot Yasser twice in the head at close range with a long-barrelled shotgun.

Giving evidence to the inquest Detective Constable Jacqui Starkey, who works in the Homicide and Major Enquiry Team of West Yorkshire Police, said it was thought the murder resulted after a series of tit-for-tat attacks between rival gangs in Keighley.

It was believed Yasser had been killed as revenge for the shooting of a senior gang member a month before.

Det Con Starkey said: “It became clear due to intelligence gathering into the group that the motive for the murder was in response to the injury of a senior member of the rival group.

“Intelligence was vague from the community, people were reluctant to speak for fear of reprisals.”

The gun has never been recovered but the Honda Accord was found burned out in Spencer Road, Horton Grange, Bradford, a short time after the attack.

Recording his verdict Mr Whittaker said: “This has always been an extremely tragic case compounded by the fact that so far no perpetrator has been brought to justice. I offer my continuing sympathy to Mr Nazir’s family.”
