Police and football fans clashed tonight ahead of Manchester United's home game against AS Roma.

Up to 100 people were involved in the street fights with Manchester Police officers at Old Trafford. Police dog units and mounted officers became involved with a series of scuffles with supporters close to the stadium's front entrance on Sir Matt Busby Way.

Fans are understood to have hurled bottles and missiles at police lines outside the ground. A group of around 1,000 mostly AS Roma supporters gathered around the main entranceway, although it is believed only 100 were involved in violence.

Some fans suffered cuts and other injuries. The violence appeared to last only a few minutes and was quickly brought under control by officers.
