A six foot, 23 stone fifth Dan Taekwondo instructor has been locked up for 16 months for a serious assault on his long-standing friend.
Garry Petrie of Kingspark was sentenced at Glasgow Sheriff Court having previously pleaded guilty to the attack.
Petrie and his partner had been celebrating a birthday with Martin and Caroline Boyle, whom they had been friends with for several years, at the Boyle’s home in Mount Florida.
All went well and there was never any indication of a problem until later that evening.
Martin said: “We had been having a nice family and friends get together to celebrate my wifes birthday. We had a few beers, chatting about holidays we had been on together among other topics.
“My wife and daughter went off to bed and at that point Garry and his partner left.
“I started lifting the glasses, and tidying up a wee bit before bed when the door went. I went to answer it and was surprised to see Garry back. I let him in and he went berserk, punching me in the face.
“I kept reminding him he was a black belt and to stop, when my daughter heard the scuffle and came down the stairs. I was leaning against the wall holding my face, she stepped in between us, and asked Garry to leave, he threw her out of the way, smashing her head against the doorframe.
“Eventually we managed to remove him but not before my wife had also been involved.”
Petrie was arrested by police who had been alerted by neighbours to the assault and was eventually charged with assault to severe injury and permanent impairment.
As a result of his injuries, Martin had to undergo reconstructive surgery for a fractured cheekbone, needed a tooth replaced, suffered injuries to two facial nerves and a detached gel-sac in his eye.
Tom Stammer. acting chief executive of British Taekwondo, said: “We are aware of this matter and are investigating.
“We are saddened that a member has failed in one of the most basic tenets of the sport, that of self-control, which was evidently missing that night.”
