Riot police armed with shields and batons had to disperse a “hostile” crowd throwing bottles at the scene of a suspected shooting and stabbing in Brixton, south London on Wednesday night.
Shielded officers stormed an estate where a party was being held, according to locals, after a man was shot and stabbed in Moorland Road.
Bottles were pelted at officers trying to maintain a cordon with the front window of a police vans smashed in the melee.
Police said they were called by ambulance staff at 9.37pm to reports of an injured man.
A 25-year-old man was found suffering gunshot injuries and stab wounds.
He was taken to a south London hospital where his condition has been assessed as not life-threatening but potentially “life-changing,” a Met spokesman said.
A 17-year-old male has been arrested on suspicion of attempted murder and remains in police custody.
At least two officers were assaulted; neither required hospital treatment, the Metropolitan Police said.
There were no reported injuries to other members of the public.
Resident Ben Fahey, 36 told the Standard, the atmosphere changed after police stormed the party.
“There were dozens of groups of young people dressed up for a party milling about but the energy was good and fun. Then I heard several bangs and a collective scream.
“It sounded like hundreds of people shouting at the same time, it was quite eerie.”
Mr Fahey said he came out of his house to see crowds confront officers after they stormed an estate to put an end to the party.
“The atmosphere completely changed to being very hostile.
“Then as I turned the corner six more vans and riot police jumped out and ran past me into the estate.
“Then everyone started to run in all directions.”
Ken Marsh, chair of the Met Police Federation representing rank-and-file officers, said bottles and bricks had been thrown.
He called on the Government and Met Commissioner Dame Cressida Dick to condemn violence against officers simply doing their jobs.
Mr Marsh said: “We’ve got to curb this sort of behaviour very quickly, otherwise if feeds into the narrative that you can bash up police officers and nothing happens. It’s unacceptable.
“Officers originally attended last night to keep the peace and protect members of the public.
“For trying to save lives, they were abused. It beggars belief.
“What is going on with society when my colleagues are facing this on a regular basis? It’s disgusting.
“It’s not all members of the public. But there is a small nucleus where officers have gone so low in their estimation since last summer, that they think we are there to be abused and assaulted.”
Superintendent Dan Ivey, who is responsible for neighbourhood policing in Lambeth and Southwark, said: “The scenes we saw last night were unacceptable. A shocking outburst of violence unfolded, in which a man sustained very serious injuries. But for the speed of the officers who responded, and the skill of medical staff, this could well have turned out to be a murder investigation.
“We are doing everything we can to support our colleagues in Specialist Crime as they investigate. Local residents can expect to see an increased police presence in the area. I urge anyone who has information that could help us to call 101 or speak to those officers and tell us know what they know. Silence protects violent criminals. Police and local communities must work together to take these people off our streets.
“The scenes that followed the initial horrific incident were equally unacceptable. The officers at the scene were working to conduct an investigation following a serious incident and were dispersing crowds when they themselves were subject to an abhorrent attack from crowds of people who pelted them with items.
“The crowds were dispersed after further resources were deployed to the scene and order was restored. The people who were involved in that disorder can be assured that there is an investigation and we will be working to identify them and bring them to justice.”
