A MAN who slashed a teenager across the face in revenge for allegedly assaulting his girl-friend has been jailed for three-and-a-half years.
Brian Ditchburn, 22, of no fixed address, but formerly of Whitby Road, was sentenced at Chester Crown Court on Tuesday.
He had admitted slashing the 17-year-old's face.
Prosecutor Meirion Lewis-Jones said Ditchburn had known the teenager as they had been in foster homes in the Chester area.
Ditchburn had punched the teen in an incident several days earlier, and there had been animosity between the two for some time.
On March 4, the teenager and a friend were drinking with Ditch-burn and his then-girlfriend in a flat in Whitby Road.
An argument developed in which the teenager punched Ditchburn and allegedly his girl-friend, whose nose was broken.
The teenager left, but was followed by an angry Ditchburn carrying a large kitchen knife he had taken from the flat.
When the teenager came out of a kebab shop, Ditchburn slashed him across the side of the face causing a 'fearsome wound' which needed 22 stitches.
The injured teenager collapsed to the floor in shock and a pass-er-by called the police.
Ditchburn still had hold of the knife when the police arrived to arrest him.
'He was walking up and down the pavement ignoring police requests to let go off the knife,' said Mr Lewis-Jones.
Officers had to spray him with CS gas and arrested him.
In interview, Ditchburn admitted the wounding charge and being in possession of the knife.
He said he had only reacted after he and his girlfriend had been assaulted and he had only intended to scare the teenager.
