Two members of staff were threatened in an armed robbery in Whalley Range.
At 1am on Monday 22 April 2014, three masked men went into The Hillary Step on Upper Chorlton Road, as staff were leaving.
They demanded money while threatening staff with metal bars.
Workers handed over money and the men ran off before it is believed they got into a car parked nearby.
One of the offenders is described as 6ft tall and medium build. He was wearing a balaclava, a dark grey hooded top and black tracksuit bottoms.
The second and third offenders were also described as 6ft tall with a medium build. They both wore balaclavas and dark clothing.
All three were holding metal bars and spoke with a Liverpudlian accent.
Detective Constable Phil Whiting from South Manchester division said: “Thankfully no one was physically hurt but all the staff members were shaken after their ordeal. To be confronted and threatened by these men holding metal bars must have been terrifying.
“I would urge anyone who may know who is responsible for this robbery or who may have seen three men acting suspiciously in the area to contact police immediately.”
