Three women are helping police with their investigation into the theft of more than $600 worth of high-end vibrators from the Libido adult store in Northbridge at the weekend.

Police allege two women removed packaging before concealing the items in their clothing during the theft at the James Street store, about 12.10am on Sunday.

Police earlier released CCTV images of three women who they believe could help with their investigation.

While it’s tempting to see the funny side of sex toy theft, it is no laughing matter for Libido owner Garry Smith, who said on average $2500 worth of goods were stolen every six months.

But, with the store boasting high-quality security cameras, any prospective thief should heed Smith’s warning.

“Without exception we will seek prosecution for every theft,” he said.

“The message is, don’t do it.”
