A 15-year-old is among four girls to have been arrested in connection with a night of widespread disorder and violence that hit London earlier this week.
Two 16-year-olds girls and a 17-year-old girl are being questioned over disorder at a McDonald’s in Marble Arch.
Two boys aged 16 and 17 and an 18-year-old man were also arrested and have been bailed until dates in early and mid September.
The arrests came after police released a gallery of photos of suspects linked to the disorder that saw three people including a police officer stabbed.
A second officer suffered injuries from a flying bottle as officers tried to contain aggressive crowds that had gathered for a water fight in Hyde Park on Tuesday.
Seven of the suspects pictured in the appeal are yet to be traced.
Scotland Yard has released a further eight images of people wanted in connection with the McDonald’s disorder.
