The 19-second clip, recorded on a mobile phone camera, shows a grinning youth ripping the glasses off a charity worker in a street of Wrexham, north Wales, and then running away while his friends roar with laughter.

The clip, posted Tuesday by "wxmboys", was titled "Wild specs robbery" and captioned: "*** up bald lad steals randomers specs in street! Absolutely WILD!!!"

North Wales Police confirmed that a spectacles theft was reported in the town on Saturday.

They viewed the footage, which clearly shows the alleged perpetrator's face, and collared their prime suspect.
