Football fans have been warned by police ahead of the upcoming Hogmanay Old Firm match.

Controversy has surrounded the decision to play the Glasgow derby on December 31 however, in September Police Scotland said the date was the "best option".

The two sides will kick off at 12.15pm on Saturday at Ibrox Stadium in what will be the first time an Old Firm match has been held on Hogmanay.

As the city gears up for a weekend of celebrations, the chief officer for Police Scotland's Greater Glasgow division has urged people to "plan before partying" and urged fans to be on their best behaviour.

Thousands of people are expected to descend on Glasgow on Saturday and police are advising the public to be responsible and plan any outings in advance.

Chief superintendent Brian McInulty said: "Much has been said about the Rangers v Celtic match taking place but I envisage that the majority of supporters will come and enjoy the game and leave safely.

"However, that small minority determined to cause disorder, anti-social or offensive behaviour will be met with the full force of the law.

"Officers will actively tackle those who put the safety of others at risk.

"Our policing approach is about early intervention, prevention and engagement and people should expect to see more officers proactively targeting the small amount of people intent on drinking to excess or behaving badly."

He added: "This is no doubt an exciting weekend for many people, whether it's to enjoy a day of shopping at the sales, attending a football match or gearing up to celebrate the New Year.

"It does mean that the city will be busier throughout the day and night. Together with our partners, we have robust policing plans in place to account for this with public safety being our priority."

Specific operations are in place for the match together with two other football matches, at Hamilton Accies and Partick Thistle, taking place in the West of Scotland.

Ch supt McInulty went on: "Given the time of year, it would be expected that alcohol will play a part in some of the activities but I would urge people to drink responsibly, plan your outing in advance and ensure you stay with friends and family who know where you are.

"Expect to see more officers in and around stadiums, shopping centres, on approaches to Glasgow and in the city centre itself.

"I completely understand that people want to have a good time and for some, that means drinking alcohol.

"However the safety of people visiting the stadium or just the city of Glasgow itself, is our priority and I would urge people not to drink when coming to the stadium, as you'll not get in.

"Drink responsibly if out later at night and keep yourself and your belongings safe. Know how you're getting home and plan it ahead.

"We want to keep people safe whilst they enjoy football, parties and celebrations as part of our Festive Safety campaign. Have a great weekend and a happy New Year."
