A woman has been left badly shaken after being injured by a knife-wielding robber in the city centre.
Detectives are investigating a report of the armed robbery at commercial premises in Shipquay Place on November 29.
At approximately 11.30pm a male, brandishing what is believed to be a knife, entered the premises and demanded that the staff member hand over money.
A struggle then ensued between the staff member and the male.
The male then made off from the premises with a sum of money.
The member of staff received a minor injury to her hand. She was left very badly shaken by this ordeal.
