Relatives of a popular biker killed in a hit and run have launched a fight to get the asylum seeker driver involved deported.

Alison Roberts is furious that Jean Renee Mukadi, 32, was not deported immediately after serving 43 days of a four month prison sentence for failing to stop and report an accident and driving without insurance or a licence.

Last June, Mrs Roberts' only brother, Simon Lawrence, 55, of High Street, Yiewsley, was killed as he rode from a meeting with West Middlesex Motorcycle Club along Harvil Road, Harefield.

The former police officer has told of her disbelief that the offence was not deemed serious enough to warrant immediate deportation back to the Democratic Republic of Congo for Mukadi.

She said: "Gordon Brown said asylum seekers that break the law should be deported, but it hasn't happened in this case. The fact is he has had his asylum application turned down three times. He broke the law and he is still here."

During the hearing last November, Uxbridge Magistrates' Court heard how father-of-one Mukadi, of Hartham Road, Haringey, fled the scene, fearing it would affect an impending appeal against a failed asylum application.

He added he was unaware Mr Lawrence had been hit. He said he had suffered depression, stress and sleep-lessness since hearing of Mr Lawrence's death.

The grieving sister has since launched a campaign and wants to see a memorial to the biking enthusiast and former marine placed on the stretch of road where he died.

"What I'm campaigning for is a change in the law. He left Simon at the side of a country road," she explained.

Friend and fellow motorcycle member, Steve Thornley, added: "I can't understand why the Government are kicking their heels at all. It should not matter how trivial a crime is, it's still a crime. I have got no faith in the Government anymore."

The UK Border Agency said Mukadi was being considered for deportation.
