Police are on the look out for an odd criminal who was caught on CCTV repeatedly sniffing the bum of a supermarket worker.

The pervert - who is balding, ginger and about 40-years-old - has been seen smelling the rears of Co-op workers in Plymouth, Devon.

Cops say he has done this at least 20 times and have released the footage of him sniffing peopled bottoms in the hope that someone can identify him.

The clip clearly shows him pretending to pick items from shelves near staff and sniffing their bum.

On one occasion he got so close his nose touched the man... guess he really did get a bum deal from Co-op.
