A THUG, who lost part of his ear in a pub brawl, knocked a man unconscious with one punch, a court heard today.

Martin Carroll, 28, floored Gary McGrevey, 48, outside The Sir John Fairweather in Glasgow’s Cambuslang in December 2018.

Carroll was also assaulted and lost part of his ear during the late-night scrap.

Carroll pleaded guilty at Glasgow Sheriff Court to the assault to Mr McGrevey’s severe injury.

The court heard one of Carroll’s friends was attacked earlier that night which sparked the wider confrontation.

The court was shown horrific CCTV of the two groups of men spilling out the pub engaged in a stand-up fight around 11pm.

Prosecutor Mark Allan said: “Carroll is seen in the footage punching Mr McGrevey on the head and he is seen falling to the ground.

“He was rendered unconscious."

Bar staff dialled 999 and police quickly arrived to find Mr McGrevey lying on the ground, unconscious but breathing.

He was taken to Hairmyres hospital for treatment to a subdural haematoma and was kept in for over three weeks.

Mr McGrevey, who was unemployed, also required speech, physio, and occupational therapy for six months.

Mr Allan told the court Mr McGrevey has “no recollection” of the incident but has since recovered.

Carroll, a joiner from East Kilbride, was later traced by police and he was arrested.

Lawyer Jackson Bateman, defending, told the court Carroll was also taken to hospital for treatment to several wounds as a result of being attacked.

He said: “Mr Carroll lost part of his ear but required no surgery.”

Sentence was deferred until next month for background reports by Sheriff Sean Murphy QC who continued Carroll’s bail meantime.
