A teenage market worker was jailed yesterday for two separate attacks.

David Kemp, 18, assaulted his first victim, Kevin Warburton, with a crook lock on November 18 last year.

Newcastle Crown Court was told how Mr Warburton was left with a 3cm wound to his head after the attack, in South Shields, South Tyneside.

In the second incident, Andrew Brydon was repeatedly punched and kicked before having his head stamped on twice as he lay on the ground outside a pub in Darlington, on New Year's Day.

Mr Brydon suffered cuts and bruises, but despite having no long-term physical injuries he no longer socialises in pubs because of the attack.

Kemp, of High Northgate, Darlington, pleaded guilty to wounding and assault. He was jailed for 21 months.

Brian Russell, defending, said since the incidents, Kemp had stopped drinking alcohol.
