At least 12 people have suffered burns as a result of a suspected noxious substance in a London nightclub packed with hundreds of bank holiday revellers.
It is understood that the incident at the Mangle E8 nightclub near Dalston, east London, early on Monday prompted the evacuation of the venue where about 600 people had been at an event. About 200 had left the premises before emergency services arrived, with a further 400 evacuated from the events space.
The fire brigade, police, ambulances and a hazardous area response team were sent to the venue and closed surrounding roads.
The London ambulance service said it had taken 10 patients to hospital, while police said another two people with similar injuries sought treatment at a hospital.
