A Hell's Angel was shot dead as he rode along a motorway at 90mph after being targeted for "execution" by members of a rival biker gang, a murder trial has heard.

Gerry Tobin died when he was struck by one of two rounds fired at him on the M40 from a car tailing him.

Prosecutor Timothy Raggatt, QC, told Birmingham Crown Court that the killing by members of a group known as the Outlaws was calculated "down to the finest detail".

Mr Raggatt said Mr Tobin, 35, a senior Hell's Angel in a London chapter of the group, was a law-abiding citizen.

The QC told jurors that Mr Tobin, from London, was a complete stranger to the men in the dock. "There is not a scrap of evidence that any of them had ever met him. That said, of course, he was undoubtedly targeted, selected and, some would say, executed," Mr Raggatt said.

Mr Tobin, a mechanic, was shot near Warwick Services on August 12 last year from a car later found burned out.

Mr Raggatt went on: "The incident was a thoroughly ruthless one executed with great skill and precision, great timing and was the product of a great deal of planning.

"It was a thoroughly carefully aimed shot delivered by someone in a vehicle. It was travelling at something like 85-90mph, approaching carefully from behind."

The jury of six men and six women was told that Mr Tobin was travelling in convoy with two other motorcycles after visiting the annual Bulldog Bash, a Hell's Angels music festival, at Long Marston, Warwickshire.

"The evidence may show us that Long Marston is in a part of the country that the Outlaws regard as theirs - part of their patch," Mr Raggatt said.

The bullet which killed him was probably fired from a revolver, while a second handgun was used to aim a shot at his rear wheel, Mr Raggatt alleged.

"There were contingencies and alternatives that had been planned for," he continued. "It was in that sense almost a military-style operation and had at its heart the plain intention to kill."

Simon Turner, 41, from Nuneaton, and Malcolm Bull, 53, from Milton Keynes, and four men from Coventry - Karl Garside, 45, his brother Dane Garside, 42, Dean Taylor, 47, and Ian Cameron, 46 - all deny murder and possessing two shotguns.

Turner and Dane Garside also deny a further charge of possessing a firearm with intent to endanger life.

The trial continues.
