Celtic striker Leigh Griffiths was caught driving at 62mph in a 50 zone, a court heard.

A police officer said the Scotland star was caught by his speed gun on Dundee's Kingsway last June.

Safety camera officer Scott Aitken told a court that the blue Mercedes was clocked "going much faster than the previous vehicle" on the stretch of road.

Griffiths went on trial on Thursday at Dundee Justice of the Peace Court after denying a speeding charge.

More than three hours' evidence was heard from Mr Aitken about the calibration of the speed gun equipment used in the van he was operating.

He told the court he set up the camera on the Kingsway's westbound carriageway around lunchtime on Saturday, June 3 last year.

Around 2.21pm he spotted a blue Mercedes heading towards his van.

He said: "As he came round the corner he is going much faster than the previous vehicle which was doing 50mph.

"I had to wait till that van passed and I had a full view of the car before I triggered it.

"It read 62mph."

Mr Aitken then pointed out Griffiths as the driver seen in a three-second video clip taken from the speed van's camera recording.

Fiscal depute Alan Kempton asked him: "As far as you were concerned all the conditions for the use of this device [the camera] were satisfied?"

He replied: "Yes."

The case was deferred until August 30, when Griffiths must appear in court - the same day as Celtic could face a Europa League play-off match.
