A MAN was cleared of knocking an off-duty police officer unconscious at a Gerry Cinnamon concert.

Lee McShane, 42, allegedly assaulted Patrick McGhee also known as Mark, 35, at Glasgow’s Hydro on December 21, 2019.

The officer told the trial at Glasgow Sheriff Court that he could only remember waking up with an oxygen mask on in a first aid room.

His friend John Jordan, 34, claimed that he saw Mr McGhee being punched on the head during the last song of the concert.

Mr Jordan added that McGhee started shaking on the ground.

The officer was later left with a scar on the back of his head after being treated with five staples.

McShane continued to deny assaulting Mr McGhee to his severe injury across two trial dates.

His lawyer Manjit Ram submitted a no case to answer submission after the Crown closed its case on Wednesday.

Miss Ram stated that the only person to identify McShane as the attacker was Mr Jordan.

Prosecutor Lauren Donnelly said that Mr Jordan was "emphatic" in his identification.

Sheriff Sean Murphy QC decided in favour of Miss Ram's submission.

He said: "There is no corroboration as Mr McShane being the perpetrator for the assault.

"Mr McShane you are acquitted of the charge and for the matter you are not guilty and free to go."

McShane, of the city's Gallowgate, replied: "Thank you" before leaving the dock.
