Nottingham Forest's mascot has been stolen from his home at the club's City Ground, the club has revealed.
The bear costume was stolen from the City Ground after a match
Sherwood the Bear was taken from the club's restaurant after a match against Rotherham on 22 September.
Three youths were spotted on CCTV footage after the bear disappeared following the Carling Cup tie, Nottinghamshire Police said.
Forest officials said they hope to find the costume so the mascot can attend upcoming charity events.
Club spokesman Matt Eames said: "We realise it might be a prank that has just gone a little bit too far, but it is important that we get Sherwood back soon.
"He is unbelievably popular and if he is not returned soon we will have to cancel hospital visits and appearances at charity events.
"A lot of children will be bitterly disappointed. "
The suit and two heads were stolen from a store cupboard in the Pitch Diner, which is part of the City Ground, police said.
Benny the Buck
The three suspects are described as white males in their early 20s.
One was of medium build with short dark hair, wearing a green parka style coat, and the second was also of medium build with short dark hair, wearing a dark jacket and light trousers.
The third man was of medium build with short dark hair, wearing a brown jacket and light trousers.
It is the second mascot hunt for Nottinghamshire Police in the past month.
They are also looking for the furry head of Benny the Buck, the mascot of AFC Telford United, which was stolen in Newark three weeks ago.
