Two teenagers have been charged with assaulting officers as revellers clashed with police an illegal rave in Hackney.
Police received more than 30 calls from residents saying there were around 300 people at an unlicensed music event on the Woodberry Down Estate from around 11pm on Friday.
When the force attempted to engage with those involved, they were met with "violence and hostility," Scotland Yard said.
Two police officers were injured.
Devonte Perkins, 18, was charged with assaulting an emergency work and using threatening, abusive, insulting words of behaviour to cause fear of violence.
He has been remanded in custody to appear at Thames Magistrates' Court on July 20.
Meanwhile, Brandon Elabor, 18, was also charged with assaulting an emergency worker and he has been bailed to appear at Thames Magistrates' Court on September 11.
The Met Police said that residents had reported noise and instances of anti-social behaviour.
After engagement and encouragement failed, specially-trained public order officers entered the estate to disperse the group.
But these were met with further resistance and items including canisters, bottles and a bicycle were thrown at police.
All those in attendance were cleared from the area by around 4am.
In a statement yesterday, Deputy Assistant Commissioner Lucy D'Orsi said: "We deployed officers to the Woodberry Down Estate N4 after we received upwards of 30 calls from residents.
"These residents were scared to leave their homes and scared about what they would face outside their front doors in the morning," she said.
"It is always an anxious moment for us as we deploy our officers into such situations but I draw confidence from my knowledge of the outstanding training they receive.
"As I waited for news last night I hoped that residents and officers were okay.
"It is always humbling to see the work of my colleagues, who tirelessly attended call after call last night to help some of the most vulnerable members of our communitie," she added.
