A man has been charged after he allegedly entered public female toilets near a Betty Burgers restaurant and filmed a woman using a cubicle with his mobile phone.

A police spokesman said the woman followed the man outside the burger shop and into the mall at Forrest Chase, in Perth’s CBD, before he fled the area about 5.30pm on September 20.

Police were contacted and quickly apprehended a Wattle Grove man, 21, who was taken into custody.

He was charged with using an optical surveillance device to record a private activity and will appear in the Perth Magistrates Court on October 21.

Detectives investigating the incident believe the man also entered female toilets inside Perth’s Myer store before he struck the toilets near Betty Burgers.

Police urged anyone who used the toilet facilities on level two at Myer between 3.45pm and 5pm on September 20 or who saw a male acting suspiciously to contact Crime Stoppers.
