Stumbling across serial offender Alexander Hockett, 34, he chased the burglar out of the house and into a garden.
Fred, 55, told the Daily Mirror: "I wanted to catch him. He stopped in a garden and told me not to touch him. I asked 'what's going on?' He said he was sleeping rough."
When Hockett ran off, Fred chased after him again, all the way to the local Wetherspoons.
But then in a strange turn of events, Fred suddenly felt sorry for the bloke who'd been ready to nick his stuff… so he bought the crook a drink.
He said: "We were both huffing and puffing and I asked 'do you want a pint?' So we both had a pint. He's not a nasty bloke. At least he wasn't to me."
When the police arrived at the scene they arrested Hockett, who has 128 previous convictions. He's since been jailed for four years.
