A MAN who pretended to be an undercover police officer to three teenagers at the TRNSMT music festival could face jail.

Stuart Robertson also pictured the 16-year-olds and followed them through Glasgow Green in July this year.

The 40-year-old pleaded guilty today at Glasgow Sheriff Court to impersonating a police officer.

The court heard that Robertson was drunk when he approached the two girls and a boy.

His lawyer Stephen Dryden said: “He told them on two occasions that he was an undercover police officer.

"He clearly wasn’t a police officer - it was drunken stupidity on his part.

“He has no recollection of what happened but accepts the evidence.”

Sheriff Tony Kelly deferred sentence for reports until next month.

He said: “This is potentially a serious matter and had the intent to deceive which is quite sinister especially with the location.”

Robertson, from Airdrie, was bailed in the meantime.
