Extra police were sent to Brixton last night as a crowd of about 150 people celebrated Baroness Thatcher's death late into the evening.
Scotland Yard said the group caused "low level" disorder and threw a small number of objects at officers, but there were no arrests and no serious injuries.
This amateur footage was uploaded to YouTube.
The Ritzy Cinema said it had nothing to do with masked people who climbed the front of the building and changed the film listings tiles to read "Margaret Thatchers dead. Equality is the key".
The group dispersed at about 1.45am, police said.
