Three arrests in Birmingham's Bullring protest

It is thought the protest was held over a US-made anti-Islam film called Innocence of Muslims

Three people have been arrested in connection with a protest in which about 100 people gathered outside Birmingham's Bullring shopping centre.

The protest, which caused the Bullring to close for several hours, started at about 15:00 BST on Friday.

It is thought the protest was held over a US-made anti-Islam film called Innocence of Muslims.

West Midlands Police said an officer was injured during the protest but did not require hospital treatment.

No-one else was injured.

A force spokesman said a 17-year-old was arrested on suspicion of affray and a 29-year-old was arrested on suspicion of affray and assaulting a police officer.

A 19-year-old who was arrested on suspicion of obstructing a police officer received a caution and was released.
