The brother of a teenager shot dead at a petrol station said this week that new five-year minimum jail sentences for illegal gun possession were not long enough.

Mohammed Sadique, (pictured) whose 16-year-old brother Yasser Hussain Nazir was murdered, said the sentences have to be long enough to stop people picking up guns - and five years isn't a deterrent.

The longer jail sentences announced by the Home Secretary David Blunkett earlier this week came in the wake of the double murders of two Birmingham teenage girls at a New Year's Eve party.

Mr Sadique, from Keighley, said: "There are people with criminal pasts who know exactly what they are about and will cut people down who get in their way.

"But there are also people who do not realise just how dangerous guns are.

"They do not realise that one pull of the trigger and a life is gone. For me, who has lost a loved one through guns, five years seems nothing."

Yasser - of Chatsworth Street - was shot dead at a filling station in Bradford in September 2001.

Keighley MP Ann Cryer welcomed the Government's tougher stance on guns.

She said: "It is important that people who think they are above the law, and use guns to instill fear in the public, are dealt with harshly."

As part of its package of proposals, the Government also wants to introduce a ban on replica guns such as air rifles which can be adapted to fire live bullets.

Fellow Labour MP Gerry Sutcliffe (Bradford South) has been campaigning for an all-out guns ban. But he said the five-year sentences were strict enough to get the right message across for now. "In the short term this is exactly what is needed," he said.

"But we also need to look at why people think guns are glamorous and tackle the gun culture itself.

"People now use guns like they used to use their fists and hands."

He said the 18-30 age group particularly needed targeting.

A police spokesman said: "While we need to see the proposals in more detail, anyone involved in gun-related crime can expect to receive a custodial sentence."

He added that the force had already enjoyed significant successes in tackling gun crime, with initiatives including weapons amnesties.

And he said the clampdown on replicas was also crucial.

"We are always very concerned about the availability of replica and imitation firearms and have made efforts to take these out of circulation," he said.
