A 34-year-old man has been charged and police are hunting others over an alleged incident at the Mandurah Forum.
A group of people allegedly stole a number of items from a store inside the shopping centre around 3pm on Tuesday, September 8.
Police allege a number of males were involved in an altercation, some of the brandishing knives before leaving the area.
A 34-year-old Mandurah man has since been charged with being armed in a way that may cause fear and disorderly behaviour in public.
Police are now looking for the rest of the people allegedly involved.
Detectives wish to speak to the male pictured, who may be able to assist with the investigation.
