Police have released 12 images of people wanted in connection with what they describe as 'disorder' at a McDonalds in central London.
A number of people jumped over the counter to take food and drinks from the McDonalds branch in Marble Arch.
In footage posted on social media, customers can be seen looking terrified before running from the restaurant.
It happened on the same night of mass violent disorder in London's Hyde Park on Tuesday which resulted in a police officer being stabbed.
About 4,000 people were on the banks of the Serpentine on Tuesday afternoon on one of the hottest days of the year so far.
However, festivities turned hostile as the evening wore on.
Three people, including a police officer, were stabbed in the violence that spilled into Marble Arch.
A second police officer was injured after someone threw a bottle.
