He put the toy - believed to be a masturbation aid - into the bag and calmly left the premises.

The electronic device resembles a woman's back side and genitalia, according to the manufacturer.

The rose tattoo on the left cheek, bizarrely, is said to have a 'life like touch', the Smoking Gun reports.

An employee is reported to have followed the robber as he left the store, inadvertently setting off the alarm.

He then tried to hide by sliding into the seat of his minivan, but the employee knocked on the window.

'The suspect ignored her, started the vehicle and then left the scene,' police said.
