Thieves have stolen a charity bucket from outside a house displaying Christmas lights for Help for Heroes.
Martin Scarrott from North Way in Oxford said he thought the bucket would be safe because CCTV cameras were focussed on it.
It had being hanging on his fence for two weeks and contained about £50 before being stolen on Monday.
CCTV footage, which has been given to the police, shows a person in a hoodie taking the bucket at about 2130 GMT.
Mr Scarrott has erected elaborate displays in his garden for the last three years and vows to continue raising money despite the theft.
"My wife felt really upset and she said, 'well I don't really want to do it anymore' but I've tried to persuade her that we're going to carry on," he said.
The bucket could not be emptied by Mr Scarrott because it was security sealed and despite being chained to the fence the thief kicked off the plastic handle.
Anyone with any information regarding the incident was asked to contact the police.
