Hundreds of revellers fled from a trendy underground nightclub in Hackney after acid was sprayed into the crowd.
At least 12 people suffered burns after a noxious substance was hurled over people inside Mangle in the early hours of Monday morning.
The basement venue in Warburton Road, Dalston was evacuated after the alarm was raised.
One witness told the Standard : “In the party in the basement there were girls making noise, I saw their friends ordering a bottle of water - they were putting it on them, they were splashing it on their faces.”
The witness added: “It was like a war - the police were everywhere.”
Police, London Fire Brigade and London Ambulance Service were called to the scene at 1.10am on Monday, April 17. A total of 12 people were treated at hospital.
Two men in their 20s remain in a serious but stable condition. The others were treated for minor injuries.
Detectives believe the attack happened after a dispute broke out between two groups of people. A noxious substance was sprayed by a male suspect, aimed at two of the victims.
The substance is yet to be identified but is believed to have been acidic.
Police said enquiries continue and there is nothing to suggest the attack was gang related.
No arrests have been made.
A statement from the nightclub said: “We are currently cooperating with the Metropolitan Police’s investigation into an incident that occurred on Monday morning. At this stage, we cannot offer any further comment.
Anyone with information should call detectives from Hackney CID via 101 or Crimestoppers anonymously on 0800 555 111.
