Old Firm match: Reward to find boy's bottle attacker
A reward of £1,000 has been offered in a bid to find the person responsible for a bottle attack on a 10-year-old boy before Sunday's Old Firm game.
Kieran Duffy was left covered in blood, lost two teeth and suffered a hairline fracture to his face.
The young Rangers fan was attacked after a group of Celtic fans surrounded the minibus he was travelling in at Cathcart Road, near Hampden Stadium.
Police said that, so far, they had received no calls offering information.
Det Insp Thom McKean, of Police Scotland, said: "A local businessman, who wishes to remain anonymous, was so appalled by what had happened that he approached police to offer a reward of £1,000 for information leading to the arrest and conviction of the person responsible.
"This comes following our appeal yesterday which unfortunately, despite the significant coverage both in the media and online, no calls have been received by Police Scotland offering any information about the incident or those responsible.
"We are of course checking CCTV and carrying out inquiries into the attack on Kieran and would encourage anyone with information, no matter how insignificant it may seem to them, to come forward."
Kieran, who was on the bus with his father Robert and twin brother Declan, told a news conference on Tuesday: "I was scared, I didn't know what had happened.
"I looked at my brother and saw he was crying. My hand was covered in blood and I realised something was wrong."
His father Robert, 39, described the attack as "a cowardly act".
Det Insp McKean added: "Someone knows who did this and should not be misguided by loyalty.
"Contact police - just imagine if this was your own child or someone you know.
"The same would apply to the man who threw the bottle - own up and contact police as it is only a matter of time before you are traced."
