Gunmen who killed a gangland figure in a Glasgow supermarket car park seemed to "know in advance" where their target would be, a court heard today.

Kevin "Gerbil" Carroll was in the back seat of a black Audi A3 outside Asda in Robroyston, Glasgow, when two masked men repeatedly fired shots into the rear of the vehicle.

Supermarket worker Alexander McBride said he saw the attack from a short distance away.

But he told the High Court in Glasgow that he was neither afraid nor felt he was in danger because the gunmen had "no interest in harming anyone else" and the attack was "obviously targeted".

He said: "To me it looked as if it was totally planned. They had no interest in harming anyone else, in my opinion. I wasn't afraid."

He added: "I was just dumbfounded. I was just standing there looking as if it wasn't happening. It was surreal."

He said the shooting was over in "15 seconds".

Mr McBride was giving evidence at the trial of Ross Monaghan, 30, who denies repeatedly shooting and murdering Mr Carroll, while acting with others, on January 13 2010.

He has lodged a special defence of incrimination, blaming a man who cannot be named for legal reasons and seven others.

Mr McBride also described how two men ran from the Audi before the gunmen opened fire. He said they returned within "five minutes" of the shooting.

He said: "They looked in (the car) and I heard them shouting - high-pitched screaming. They were upset, obviously. As if they couldn't believe what had happened."

Derek Ogg QC, defending Monaghan, asked Mr McBride: "These men wanted one thing and one thing only: firing at whoever or whatever was in the seat in the back. They had no interest whatsoever in the two who got out of the Audi?"

He replied: "Yes."

Mr Ogg went on: "Did it seem to you that the two people who got out, masked, from the car all along knew it was the back-seat passenger, almost as if they knew in advance they would be in the back seat?"

Mr McBride said: "Yes."

Monaghan is also alleged to have attempted to defeat the ends of justice by concealing a revolver, a pistol and ammunition under bricks and undergrowth in Academy Street, Coatbridge, North Lanarkshire, and setting fire to a car.

He is further charged with possessing guns and ammunition without a proper certificate.

Monaghan denies all the charges against him.

The trial before Lord Brailsford continues.
