Officers investigating the disappearance of the two cameras from outside a disco in the German state of Bavaria had to do little more than watch footage caught by the third one to find the culprit.
The man was a regular at the disco, so police saved themselves a drive to his house and waited until Friday night when he went dancing again, to make their move.
A police spokesman said on Saturday that the stolen cameras had been found in the flat of a friend of the man.
He told them he was having problems in his relationship although could not explain the connection to the stolen cameras.
