Three men have been arrested and three vehicles have been seized in connection to the shooting death of a Canadian biker on a busy English highway, British police confirmed Wednesday.

Gerald Michael Tobin, 35, of south London was riding the M40 through the central England county of Warwickshire when he was shot and killed in broad daylight on Aug. 12, after leaving the Bulldog Bash motorcycle festival -- a Hells Angels biker convention.

Warwickshire police believe a green Rover 600 series car was used by the suspects to carry out the shooting.

Police have not released the identities of the three men, arrested early Wednesday morning.

However, they have confirmed that two addresses in Coventry and one in Nuneaton were raided.

"The men have been taken to a police station in Warwickshire where they will be questioned later today by detectives investigating Mr. Tobin's murder,'' Warwickshire's Assistant Chief Constable Bill Holland said Wednesday.

Police have also said that "further premises may also be searched."

A number of items, including multiple bladed weapons and one firearm, have already been recovered from the raided homes.

Police also confirmed that two vehicles, a van and a Rover car, were seized from addresses visited earlier Wednesday.

A second, fire-damaged Rover car was recovered prior to Wednesday's arrests and is also being forensically examined. Police are not releasing details about when or where the vehicle was found.

Holland called the investigation "active and ongoing."

"We continue to appeal for information -- particularly from motorists who may have seen a dark coloured Rover 600 series car on the A46 or M40 between 2 p.m. and 3 p.m. on Sunday afternoon August 12,'' he said.

Police have previously said that a green Rover 600 series car, with two or three people inside, 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.

The car was travelling at more than 112 kilometres an hour when shots from within the vehicle were fired at 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. The green Rover kept driving.

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. 10 years ago, 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.

Tobin's mother, Maria, flew to Warwickshire from her home in Alberta, Canada and issued a statement via local police.

She said she feels "betrayed by life itself" and "robbed of the most perfect light."

Warwickshire police are also reexamining a similar six-year-old case.

It was on the same stretch of road in 2001 that a Canadian was shot as he rode home from the Bulldog Bash. He was wounded in the leg but recovered. The gunman was never found.

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.
