This was the moment police charged at a group of revellers outside an illegal rave in Lambeth.
Screams can be heard as officers in riot gear move towards the large group gathered at the junction between Black Prince Road and Lambeth Walk.
The "Scumoween" rave, which was shut down this morning after prolonged clashes between police and would-be ravers, was taking place yards away in Whitgift Street.
Other footage from the scene shows an angry mob throwing chairs, bottles and propane tanks at police.
Scotland Yard said a suspected petrol bomb was also launched at officers. Four suffered minor injuries.
It is not clear yet how many people were arrested.
Crowds first gathered on Black Prince Road at Albert Embankment before midnight, before dispersing down Lambeth Road on to Lambeth High Street and nearby Whitgift Street.
Police said they had posted officers at junctions to Whitgift Street to "to prevent any escalation" of the trouble.
Scumoween: A Nightmare On Scum Street had been advertised on Facebook to take place in Whitgift Street beginning at 8pm on Halloween night and lasting all weekend.
Of 13,000 invited guests on the social networking site, 4,000 said they planned to attend.
The free event was due to feature music "from the full spectrum of underground dance".
In a warning on Wednesday to those due to attend, organisers Scum Tek said: "This party is going ahead, stay peaceful, stay calm. Patience and numbers is in our favour. Do not antagonise the police. We don't need to. At the end of the day we want to leave them remembering our good attitudes, we just came to dance, we are not their enemy."
