Birmingham Crown Court was also told how two gunmen, allegedly from the rival Outlaws gang, fired at the Hells Angel from a car on the M40, on August 12 2007.

In his opening address to a jury trying six men for the murder, Timothy Raggatt QC alleged Mr Tobin was followed on the A46 near Stratford as he returned home to London from the Biker Bash festival

After showing the jury CCTV images of a Rover saloon alleged to have been used in the killing, Mr Raggatt explained how the gunmen waited on the road for a "suitable target to come along".

Mr Raggatt said the Rover then followed a convoy of three motorcycles, led by Mr Tobin, onto the M40 at junction 15 near Warwick.

A computer-generated reconstruction of the shooting showed the car pulling alongside the convoy.

Mr Raggatt claimed two gunmen fired a shot each at Mr Tobin, one hitting his motorcycle, the other hitting him in the neck and passing through his spine and skull, killing him instantly.

The 35-year-old mechanic from Mottingham, London, then fell from the motorcycle, which hit a verge. Mr Raggatt said: "What was done was carried out with precision and timing.

"Mr Tobin was selected as a target because of who he was - a 'fully patched' Hells Angel."

Mobile phone records were also shown to the jury showing calls between the defendants in the minutes after Mr Tobin's death.

Mr Raggatt alleged that these were made to inform other gang members that the "job" was done and that they could stand down.

He added: "It was a precise piece of shooting and not, as you may think, a lucky shot."

Simon Turner, 41, from Nuneaton and 53-year-old Malcolm Bull, of Milton Keynes, are on trial along with four men from Coventry - Karl Garside, 45, his brother Dane Garside, 42, Dean Taylor, 47, and 46-year-old Ian Cameron.

All deny murder and possessing two shotguns. The defendant's exact addresses cannot be published for legal reasons.

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

A seventh defendant, Sean Creighton, 44, from Coventry, last week admitted the murder and firearms offences and will be sentenced at the end of the six-week trial.

The prosecution alleges that Creighton and the six defendants were members of the South Warwickshire chapter of the Outlaws, who had a club house at a motorcycle parts shop in Coventry.
