Two men have been convicted in the murder of Gerald Michael Tobin, a Canadian biker who was shot dead on a highway in Britain last year.

Tobin, 35, was riding the M40 through the central England county of Warwickshire when he was shot and killed in broad daylight on Aug. 12, 2007.

He had just left the Bulldog Bash motorcycle festival -- a Hells Angels biker convention.

On Tuesday, Simon Turner, 41, of Nuneaton, and Dane Garside, 42, of Coventry were convicted of murdering Tobin, the BBC reported.

Turner and Garside, both members of rival biker gang The Outlaws, were also found guilty of a firearms charge, according to the report.

Four other men accused in Tobin's murder are still awaiting verdicts.

Sean Creighton, 44, of Coventry, has already admitted to the murder.

Police have previously said that a green Rover 600 series car started following Tobin and two other motorcyclists as they returned from the festival.

Several kilometres later, the green car overtook two of the three motorcycles and came close to Tobin.

Two shots are believed to have been fired, and one of those struck Tobin on his head just below his helmet.

Tobin fell off his motorcycle, which continued to career another 200 yards down the road.

Autopsy results show Tobin died of a single gunshot wound to the head.

Tobin was born in England but moved to Canada as a boy.

After moving back to the U.K. in the late 1990s, Tobin worked at a Harley Davidson dealership in south London as a mechanic.

Police have confirmed that Tobin had no criminal record in the U.K. or Canada.

Every summer, the Hells Angels stage the popular Bulldog Bash, which attracts approximately 40,000 motorcyclists from around the world for a four-day party at the Long Marston Airfield, near Stratford-upon-Avon.
