Glasgow Rangers fans battled with riot police after a big screen showing their team's match broke down moments before kick-off.

Fifteen police officers, as well as a police dog, were injured. A supporter of Rangers' Russian opponents Zenit St Petersburg was stabbed, but his injuries were not life-threatening..

CCTV footage released today shows how a lone officer suffered a broken arm as he was tripped up and stamped on by baying Scottish fans. Click the PLAY button above to watch.

The officer was among seven riot officers seen retreating down a city centre street at about 10.15pm yesterday as they were vastly outnumbered by charging supporters.

CCTV images show the officers attempting in vain to keep the fans at arm's length as missiles of cans, bottles and rubbish are thrown at them.

Six of the officers eventually turn and run but one of the officers confronts the front of the pack. He is punched before one of the mob trips him up and he falls to the ground.

The male officer is then set upon in Newton Street by a gang of about 20 fans who kick and stamp on him on the ground.

He eventually makes his escape as a stream of fans proceeds onwards, several with their arms aloft in celebration.

Greater Manchester Police said the officer suffered a broken arm and was recovering from his injuries.

In other footage released by police, a large group of supporters are seen to vandalise a car near a set of traffic lights as they smash the windows of the vehicle.

Police and council chiefs say a small minority of yobs were to blame for the violence, which started when a screen in the city's Piccadilly Gardens failed to work after a "technical signalling problem".

The screen was one of eight provided around the city by Bradford firm Lightmedia Displays to accommodate more than 100,000 who travelled from Glasgow without tickets for the game.

Rangers lost the game 2-0.
