A CCTV picture has been released of a man police want to speak to in connection with an incident believed to have taken place when the Rangers and Celtic clashed at Ibrox.
Police Scotland think this man may hold information about the incident of 'culpable and reckless conduct' understood to have taken place on Sunday, April 3, last year.
The man is described as white, in his late teens to early 20s, dark hair and wearing a dark top.
