In a statement the Metropolitan Police said: “Officers responded to reports of a group fighting on Primrose Hill at 20:26 on Friday, 31 July.
“During the incident, some individuals threw bottles towards the police.
“One person aged under 18 was arrested on suspicion of assaulting an emergency worker but was later de-arrested.
“A second person, a 16-year-old girl, was found in possession of cannabis and will be given a community resolution.
“The group was dispersed.
"A teenage girl who is believed to have consumed illegal drugs was taken to hospital by the London Ambulance Service."
There have been community concerns about antisocial behaviour at Primrose Hill.
In June a dispersal order was issued to tackle crime and antisocial behaviour.
Lasting several days, it gave police powers to ask individuals to leave the area if they have reasonable grounds to suspect they are contributing to public alarm, harassment, distress, or crime and disorder.
The measure followed concerns about increases in antisocial behaviour during warmer weather.
