Two police officers were injured as they broke up a party in Chelsea which involved around 200 people.
The event, which was branded 'incredibly selfish', took place in one of the most expensive neighbourhoods in London after the force received reports of a mass gathering at around 3.30am on 17 January.
But when they attended to break up the party, at Beauchamp Place, some of those attending became hostile and pushed through, causing two police officers to sustain injuries.
