Singer Gloria Gaynor has praised the policeman who entertained a pub crowd with her hit song I Will Survive after being called in to deal with a brawl.
Sergeant Jon Harris belted out the 1978 disco anthem while in full uniform to cheers from drinkers at Glasgow's Waterloo Bar.
Mr Harris was called to the Argyle Street pub on Wednesday evening following reports of an alleged assault and a 23-year-old man was arrested.
The policeman later agreed to take to the stage and a senior officer has credited him for ''helping defuse any simmering tensions''.
The video of Sgt Harris' performance went viral on social media.
Gaynor tweeted "I love this! Sgt Jon Harris sang #iwillsurvive to smooth tensions in Glasgow pub after a brawl'', and added a link to the Press Association story which appeared online in The Courier.
Chief Inspector Mark Sutherland, area commander for Glasgow city centre, said: ''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.''
