POLICE officers have escorted thousands of chanting Celtic fans to Park head ahead of the Old Firm match.

Supporters, some letting off green flares, sang and clapped as they made their way to Parkhead this afternoon.

As previously reported by the Evening Times, fans have been warned to behave themselves ahead of the showdown.

Superintendent Simon Jeacocke told the Evening Times: “There’s always a real sense of anticipation for these matches. It is something that we look forward to, but there’s going to be a significant policing operation in place.

"As a result, we’ve called in specialist resources from all around the country, so we’ve got public order, trained officers, mounted officers and dog branch officers available to me, as well as conventional police officers that will be working at this game.”

It was already announced that Rangers fans would be held inside the stadium for around 15 minutes after the final whistle.
