A 10-year-old boy going to his first Old Firm game was hit by a bottle thrown into a minibus by a man wearing green clothing, police have said.

The boy was taken by ambulance to Yorkhill Hospital in Glasgow where he was treated for a hairline fracture to his face and has three teeth missing. He has since been released.

Police appealed for information about the "appalling assault", which they said happened at 12.15pm on Sunday while the boy was in a Ford minibus sitting in traffic at Cathcart Road near to Nutberry Court, Mount Florida.

He was struck by a bottle thrown into the bus by a group of men who had surrounded it and were hurling abuse at the occupants.

The man who threw the bottle is described as white, 5 ft 11 in height, of heavy build and was wearing green clothing and possibly a white beanie hat.

He and the men he was with continued along Cathcart Road and into Cathkin Park towards Hampden Park.

Detective Constable Kenneth MacEwan, Cathcart CID, said today: "This was an appalling assault on the boy who was with his dad and fellow supporters going to his first Celtic V Rangers game. He never got to the match but instead was detained overnight in hospital and has a facial injury and teeth missing.

"We do believe that this was football related. Yes, it would appear that the bottle was deliberately thrown at the minibus, however, we don't think the boy was specifically targeted as such.

"Obviously Cathcart Road was very busy at this time so plenty people would have been about when this happened. I would appeal to them or indeed any of the group which we believe the man was with, to contact police.

"Anyone with information can contact officers at Cathcart CID via the non emergency number 101 or Crimestoppers on 0800 555 111 where information can be given in confidence."
