Nightclub knife attack CCTV released

An innocent bystander was slashed down the face and left with a horrific scar after being attacked by a knife-wielding man.

The assault happened when the man - believed to be 35-year-old Darren Cohen - began attacking a group of males in a Cheltenham nightclub.

He barged his way into the group, swinging his arm and the knife.

He failed to injure his intended target but caught another man - Eric Harrison - in the process, inflicting serious facial injuries.

But, the offender is still at large more than a year after the vicious incident took place.

Police have now released CCTV footage of the attack on the anniversary of the assault at the former Zest nightclub in Cheltenham.

Crimestoppers is also offering a reward of up to £1,000 for information that leads to a conviction.

Warning, this CCTV contains footage of the attack.

Cohen, who's from Hempsted, has strong links to Wolverhampton, and it is believed he may be using a false name.
