Police were called around 5.35 pm local time to a Vue Cinema hall in Birmingham amid reports that a “group of people with machetes” was storming the Star City entertainment complex.

Videos of the incident have emerged on social media showing multiple police cars arriving at the scene.

Officers can be seen intervening to keep rival groups apart during the showdown.

About 50 police cars and over 100 officers were scrambled to deal with the suspected riot, witnesses say.

A number of police officers were assaulted as they moved in, and several people have been arrested. It is unclear if any machetes were recovered, though.

The disturbances broke out ahead of the Frozen screening at the cinema, as it was packed with children, dressed up as their favorites characters. A woman who said she was present at the cinema said in a Twitter post that the commotion originally began as a fight between “young girls.”
