A man who moaned about his face on a "wanted" poster to the police was arrested for the crime.
Nicholas Allegretto, 23, complained to Cambridge constabulary that shopkeeper Neil Mackay had ruined his life after the notice went viral on Facebook.
The poster read: "Mr Magnet Man was apprehended by one of our staff stealing a valuable magnet from the shop.
"All our staff have been shown the image (N.B without the lines). You know who you are. Please be aware we will prosecute shoplifters."
Unfortunately for Nicholas his family and friends recognised him and he was sacked from his job before he unwittingly handed himself into the police.
