Police officers have been attacked while attempting to disperse crowds at an illegal party for the second night in a row.
The Met Police said objects were thrown at officers at an “unlicensed music event” in Notting Hill, west London, in the early hours of Friday.
It comes after “appalling scenes” of violence at a street party in Brixton on Wednesday evening.
Police said the majority of those in attendance had dispersed by 02:00 BST.
Earlier, Kensington and Chelsea Police tweeted that objects were thrown at officers dispersing the crowd at the event near Colville Gardens.
“Violence will not be tolerated & units are responding appropriately,” the force said.
The Met later said there had been no confirmed reports of serious injuries.
Meanwhile, officers also attended another unlicensed music event at Streatham Common on Thursday evening.
The force tweeted that officers had “engaged with a large number of those in attendance and the crowd has now almost entirely dispersed”.
On Thursday evening, Scotland Yard said it was undertaking an “enhanced policing operation” across the capital to ensure there was an “effective and prompt response to any reports or disorder”.
Commander Bas Javid said the move was “in direct response to concerns expressed by our communities, many of whom were scared and shocked by the events taking place outside their homes.”
Extra police officers in protective gear were dispatched following “appalling scenes” of violence at a street party in Brixton on Wednesday.
Scotland Yard said it was targeting further unlicensed music events and block parties around the city after 22 officers were injured on the Angell Town estate.
Footage on social media showed police vehicles smashed and officers pelted with bottles during clashes with a large crowd, with Downing Street condemning the scenes as “appalling” and Home Secretary Priti Patel calling the incident “utterly vile”.
