A police officer who entertained revellers with a karaoke classic after dealing with a bar brawl has been praised by his bosses.

Sergeant Jon Harris belted out Gloria Gaynor's I Will Survive while in full uniform to cheers from drinkers at the Waterloo Bar on Argyle Street, Glasgow.

Mr Harris was called to the pub on Wednesday evening following reports of an alleged assault.

A 23-year-old man has been arrested.

The police officer later agreed to take to the stage and a senior officer has credited him for "helping defuse any simmering tensions".

Chief Inspector Mark Sutherland, area commander for Glasgow city centre, said: "A full and thorough investigation led to the arrest of a 23-year-old male, who is expected to appear at Glasgow Sheriff Court on Thursday.

"Once the inquiry had concluded and the victim's safety ensured, Sgt Jon Harris from our city centre community policing team was encouraged to participate in karaoke ongoing in the pub.

"Sgt Jon took to the stage, which helped to defuse any simmering tensions in the pub. I was pleased to see that once the incident had been professionally concluded, my officers were able to share a lighter moment with those who remained in the pub."

Peter McKenna-Boyd, who filmed the performance, said: "Everybody just loved it."
