The killers of a Hells Angel biker waited in a lay-by near a motorway junction to select him as a target for execution, a court has heard.

Birmingham Crown Court was also told that Gerry Tobin was fired at by two gunmen from the rival Outlaws gang on the M40 in Warwickshire after pulling into the middle lane to allow their speeding car to pass him.

Continuing his opening address to a jury trying six men accused of murder, prosecutor Timothy Raggatt QC alleged that Mr Tobin was first spotted by his killers on the A46 near Stratford-upon-Avon.

After showing the jury CCTV images of a Rover saloon alleged to have been used in the shooting, Mr Raggatt told the court: "The car that ultimately was to contain those who directly killed Mr Tobin in effect lay in wait in a lay-by for a suitable target to come along.

"The evidence shows plainly that the Rover car... had positioned itself quite deliberately and waited in that lay-by. They waited until a target came by."

The Rover, containing three men, then followed a convoy of three motorcycles, led by Mr Tobin, on to the M40 at junction 15 near Warwick, Mr Raggatt said.

The jury saw a computer-generated reconstruction of the shooting, which showed the Rover passing two of the bikes in the convoy before pulling alongside Mr Tobin.

Detailing the exact circumstances of the killing, Mr Raggatt told the jury: "The car closed up on Mr Tobin and there were two shots. Both shots, you may come to think, were carefully aimed.

"There were clearly two gunmen because one gunman would not have had an opportunity to take such careful aim twice with different weapons and at different parts of the target."

One of the shots hit Mr Tobin, from Mottingham, south-east London, in the neck and passed through his spine into his skull.

The 35-year-old, who was returning home from the annual Bulldog Bash festival at Long Marston, near Stratford-upon-Avon, then fell from his motorcycle, which careered onto a verge.

Mobile phone records were also presented to the jury, showing communication between some of Mr Tobin's alleged killers in the minutes after his death.

Mr Raggatt alleged that the calls were made to notify gang members in other vehicles that the "job" was done and that they could stand down.

"What was done was carried out with precision and timing and very carefully," Mr Raggatt added. "Mr Tobin was carefully selected as a target because of who he was - a 'fully patched' Hells Angel.

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

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

The exact addresses of the defendants, who all deny murder and possessing two shotguns, 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, 44-year-old Sean Creighton, from Coventry, pleaded guilty to murder and both firearms charges last week and will be sentenced at the conclusion of the six-week trial.

The Crown alleges that the six defendants on trial and Creighton constituted the entire membership of the South Warwickshire chapter of the Outlaws, which had a "club house" at a motorcycle supply shop in Coventry.
