A thirteen-year-old girl has pleaded guilty to threatening unlawful violence during a protest in the UK. 

The event took place during a week of unrest over asylum seekers and illegal migrants, and follows two twelve-year-old boys pleading guilty to other offences in a similar riot. 

UK Correspondent Gavin Grey told Ryan Bridge the girl was among a crowd gathered outside a hotel used to house asylum seekers, and was seen punching and kicking at the entrance of the hotel. 

He said that a police officer was injured when disorder broke out at the demonstration, and there was roughly 200 protestors there.
