A MAN who stabbed a teenager after being tormented by youths has been jailed for three years.

Derek Manson, 53, and other residents in Glasgow's upmarket Hyndland area, had been subjected to a long campaign of anti-social behaviour by teenage gangs.

Manson snapped when he was verbally abused by a mob, moments after catching a boy urinating next to his home.

Glasgow Sheriff Court heard he went out with a kitchen knife, and stabbed one youth after a violent struggle.

Manson had admitted assaulting 16-year-old Darren Foy to his severe injury, permanent disfigurement and to the danger of his life when he appeared at Glasgow Sheriff Court last month.

Sentencing him today, Sheriff Robert Anthony said: "Notwithstanding the trouble in the area, courts cannot condone matters being taken into your own hands.

"You went out armed with a lethal weapon. A message has to go out that those who are prepared to go out armed and assault others must be dealt with appropriately."

Manson - a first offender - looked pale as he was lead to the cells to start his sentence.

The trouble had flared when one of a gang of youths urinated near Manson's flat in Novar Drive last June 16.

Manson opened his window and yelled at the youths to go away, but they swore at him, telling him to go back to bed.

He left his flat armed with a kitchen knife and followed the group into Hyndland Road, where he confronted Mr Foy, who then assaulted him. A violent struggle followed, during which Manson stabbed the teenager.

Manson surrendered himself to police soon after the attack, telling them: "I am the man that you are looking for." He also said it had been "a moment of madness".

Mr Foy spent more than two weeks in hospital as a result of the incident, and suffered blood poisoning.
