Nine officers have been injured and nine people have been arrested following an unlicensed music event in Barking.
At approximately 21:45hrs on Saturday, 18 June, police were informed of a large number of people gathering for an unlicensed event at a building on Thames Road in Barking.
Officers from a number of surrounding boroughs and the Pan-London Taskforce (the Territorial Support Group and Dog Support Unit) attended the scene and found approximately 1,000 people inside the venue and around 1,000 people outside the venue.
Missiles were thrown at officers.
The majority of those in attendance dispersed and the building was emptied by 02:00hrs on Sunday, 19 June.
Eight male officers and one female officer – two sergeants, two dog handlers and five police constables – received injuries. Four of the male officers were treated in hospital. Their injuries are not serious and they have since been discharged.
Nine males – no further details – have been arrested in connection with this incident. They remain in custody.
Officers remain on scene and road closures are in place.
Temporary Chief Superintendent Sean Wilson, Borough commander for Barking & Dagenham, said: “A number of officers were injured whilst going about their duties and this will not be tolerated. A full investigation has been launched and we will endeavour to bring those responsible to justice.
“We are working very closely with the community who are shocked by these events.”
Acting Inspector Matthew Laffan, added: “There will be closures for the remainder of the day in the area.
“I would like to thank the local community and businesses in the area for their cooperation and continued support as we continue to investigate the incident.”
