The city council received complaints the Shimmy night club has a "spy mirror" installed so patrons can see movement and activity in a women's restroom, the British newspaper The Guardian reported Monday.
A visitor to the club, identified as Amy, told the newspaper she noted customers in the club's main room could glimpse inside the restroom, saying men "were up against the mirror and making gestures."
"What is even more vulgar is that the toilets face onto a private booth that can be booked out [reserved] to specifically leer into the girls' bathrooms while the girls are unaware they are being watched," Amy's complaint to the G1 Group, owners of the nightclub, said.
The Scottish newspaper Sunday Express reported several women protested the mirror after photographs appeared, showing male guests with a clear view of women at a row of sinks in the restroom.
A city council spokesman said its licensing officers would visit the club, and Police Scotland, the country's police force, confirmed it had opened an investigation, The Guardian said.
