A pensioner was gobsmacked when he discovered a mouse had been tidying his garden shed at night.
Stephen Mckears, from Severn Beach, South Gloucestershire, became curious when he noticed items moving in his shed last month - even thinking it might be a ghost.
He eventually roped in neighbour, Rodney Holbrook, 70, to help him get to the bottom of the mystery.
At first the retired technician spotted that plastic clips were being placed in an ice cream tub - which he uses to feed the birds - but over time he realised there were objects piling up.
Every night for a month they found large screws, plastic leads, nuts and bolts all neatly filed away.
But who was doing it?
For fear of losing his sanity, 72-year-old Stephen and his pal decided to rig up a camera and find the culprit once and for all.
The men were stunned when the black and white footage showed an adorable little mouse busily tidying the shed - even attempting to lift objects twice his size.
Joking, Stephen said: "I've been calling him Brexit Mouse because he's been stockpiling for Brexit.
"The heaviest thing was the plastic attachment at the end of a hose pipe - and the chain of an electric drill.
"I didn't know what it was at first. The kids were saying it was a ghost.
"One day I emptied the tub out and spread the contents on the side - and the the next day they were all back in again. I thought I was going mad."
Rodney, who lives just a few minutes drive from his friend, is a keen wildlife photographer and said he had to see the DIY mouse for himself.
He said: "I've been calling him Metal Mickey but some people have been saying he's just mouse proud.
"I was quite amazed to see it. The mouse was chucking things into the box - we thought it was a ghost or something at first. I thought I have to see this for myself."
The pair filmed the mouse tidying away the metal objects from around midnight to 2.30am - which it had been doing every night for around a month.
And Stephen says it's still doing so today.
He added: "It was doing it for about two hours that night - he must have had to go for a sleep after it.
"I've seen a mouse moving objects to make a nest but never metal objects. It's quite amazing.
"It's still busy doing it now."
