[D]etectives are investigating an incident in which acid was sprayed inside licensed premises in Hackney.
Police were called to the premises in Sidworth Street, Dalston, at approximately 01:10hrs on Monday, 17 April, after members of the public complained of a noxious substance.
London Fire Brigade and London Ambulance Service were also called to the scene.
A total of 12 people attended hospital suffering burns. Ten people were taken by ambulance and two people presented themselves at an east London hospital.
Two of those injured – Victims 1 and 2; both men aged in their 20s – remain in a serious but stable condition. The others were treated for minor injuries.
Officers believe a dispute between two groups of people developed inside the venue, resulting in a noxious substance being sprayed by a male suspect directly at Victims 1 and 2. Other people inside the venue suffered the effects of the substance.
The substance is yet to be identified, but it is believed to have been acidic.
A police investigation is underway. There has been no arrest at this early stage and enquiries continue. There is nothing to suggest that this is gang related.
Anyone with information that may assist police should call detectives from Hackney CID via 101. To remain anonymous, call Crimestoppers on 0800 555 111.
