As part of an ongoing operation, several officers on foot will be on the lookout for suspicious activity around the CBD�s main shopping precincts.
Senior Sergeant Brendan Moore said he hoped the highly visible presence would help deter anti-social behaviour, which was becoming a major issue for stakeholders in the City.
�The mall is obviously a focal point for people coming into the City and people tend to congregate there and engage in disorderly conduct, including drinking and stealing,� Sgt Moore said.
�As a consequence of that, it was having a big effect on local retailers.�
Snr Sgt Moore said Myer was one of the worst hit department stores and police would be working closely with it to reduce theft.
A Myer spokeswoman said the store took shoplifting very seriously.
�We have implemented a number of measures to prevent theft and fraud in our stores, including in our Perth store,� she said.
�We have over 6000 high definition CCTV cameras across our network, including about 70-100 cameras in our Perth store to monitor and identify suspects and provide evidence in the event of a prosecution.
�Myer supports initiatives that help to make the city a safe and secure place for all.�
