Gangs of masked youths have gathered in Birmingham city centre and some shop windows have been smashed.

A McDonald's restaurant, close to the city's cathedral, has had a window broken and eyewitnesses have reported more damage in the Colmore Row area.

West Midlands Police said it was aware of some disorder, including vandalised shops and incidents of theft.

Nine people have been arrested, a spokesman said.

An eyewitness took footage of people going in and out of damaged shops in Birmingham's city centre during the disturbances.
