Police say they are continuing to make enquiries into an aggravated robbery in the Christchurch suburb of Riccarton at the weekend.
In the early hours on Sunday morning a man walked into Trevinos Bar and Restaurant on Riccarton Road with a firearm and threatened an employee before taking off with cash.
The police have today released a CCTV image of the man, who was wearing a black hooded jacket, a ski glove on his left hand and jeans.
Detective Senior Sergeant Mark Worner said police want to identify the man and asked anyone with information to come forward.
"Police also want to speak with anyone who was in the area between 11pm on Saturday and 1am on Sunday," he said.
