A DRIVER died from a “catastrophic head injury” after shots rang out as he sat in his car at traffic lights, a court has heard.

Taxi driver Rustam Saddiq, 25, told the High Court in Glasgow on Wednesday that two shots rang out he drove towards the junction of Shields Road and Scotland Street, Glasgow, on November 15, 2016.

Seconds earlier, Mr Saddiq told the court an Audi Q5 overtook him in St Andrews Drive going at 40 to 50 mph.

As he approached the traffic lights at Shields Road, he saw the Audi Q5 stopped at the lights alongside an Audi RS4, driven by Euan Johnston, when he heard two shots.

It then sped off into Scotland Street.

Mr Saddiq said he saw the RS4 crash into metal barriers at the side of the road after which he saw someone get out the passenger door to assist the victim.

His friend Mr Mohammed phoned the police and went over to try to help.

Mr Saddiq was giving evidence at the trial of Anthony Ruthven, 32, and David Scott, 33, who deny murdering Euan ‘EJ’ Johnston in Kinning Park by shooting him.

Prosecutors claim the pair – while acting with others unknown – repeatedly discharged a firearm at Mr Johnston.

Ruthven also faces a separate attempted murder and assault charge in connection with alleged incidents on August 12 2016.

Paramedic David O’Hara said he received a call at 11.47pm to attend the incident following a report of gunshots. He said he went over to Mr Johnston's car and found him slumped over the steering wheel.

He said: “I examined the man briefly and came to the conclusion he had suffered a catastrophic head injury.”

Mr Johnston was taken to the Queen Elizabeth University Hospital by ambulance and was pronounced dead at 2.50am.

The trial before judge Lady Stacey continues.
