A young Rangers fan has told of his shock after he was hit in the head with a bottle as he made his way to Hampden for Sunday's League Cup semi-final.

Kraig Mackay, 11, was looking forward to attending his first Old Firm match with his uncle when he was struck with a thrown bottle in an "abhorrent" attack.

He told STV News he was bleeding from his head and asked: "Why would somebody do it?"

Police are investigating the attack and Kraig's mother has urged whoever was responsible to "own up to what he has done."

The supporters' bus he was on had broken down near Hampden and the group walked the rest of the way to the stadium.

He was hit after a group of Celtic fans left a pub near to where Kraig and other Rangers fans were walking.

Kraig said: "We were walking up Curtis Avenue and Celtic fans were there, talking and laughing, and it was all fine.

"When we got to the junction with the main road they all started singing and pointing at us. My uncle said just hold my hand and walk past."

Police horses then moved in and it was at that point Kraig was struck.

Kraig said: "I saw liquid go everywhere and I heard a smash. I was shocked and I didn't really know what happened.

"As soon as it happened my uncle grabbed me and hugged me and put a scarf to my head to stop the bleeding."

Kraig was treated by police paramedics and then taken to hospital where he was given stitches.

He added: "I was pretty upset that we were missing the game because we had good seats. Why would somebody do it?"

His mother Laura Mackay has urged whoever is responsible to come forward.

She said: "I just hope that he would own up to what he's done. He should be totally ashamed of himself.

"Think twice before you do something, think of the consequences."

The 11-year-old, from Dennistoun, said the incident has not put him off going to Rangers matches and he will be sitting in the directors' box at the next game.

Rangers manager Mark Warburton has said Kraig will be the club's mascot at the next fixture.

Police do not believe he was specifically targeted but said the attack was "mindless."

Chief superintendent Brian McInulty said: "Whilst the majority of genuine football fans behaved well yesterday, from a crowd of 50,697, there were 18 arrests for minor public disorder including having had too much to drink.

"However, the incident involving the assault of the 11-year-old boy whilst he was walking to the game is completely unacceptable and understandably has shocked the communities of Glasgow.

"Let's be clear - this was an attack on a young boy who could possibly be left with a scar. This is abhorrent, and the person or persons responsible need to be caught."

He added: "A football game is not an excuse for violence, ever. My detective officers are continuing inquiries into the incident, and I would re-iterate their appeals for information.

"Any genuine football fan would not take part in such mindless violence, particularly throwing a bottle into a crowd with the intention to deliberately hurt someone, that person ultimately being a child.

"As I had mentioned before, genuine football fans have had enough of this type of behaviour. We've had enough of this type of behaviour and it won't be tolerated.

"I'd like to thank the majority of 50,697 football fans who behaved well and enjoyed the game."
