Hackney acid attack: Second victim has been left blind in one eye after a substance was thrown over clubbers in a nightclub

A second victim has been left blind in one eye following a horrific acid attack at an east London nightclub.

Police say a man suffered burns when a noxious substance was sprayed into a crowd of revellers at the Mangle club in Hackney.

Itt emerged earlier this week that a 22-year-old woman was also left blind in one eye in the terrifying scenes in Sidworth Street on Bank Holiday Monday.

A woman, 33, has been arrested on suspicion of firearms offences after officers carried out a raid at an address in Hertfordshire in connection with the investigation.

Two other properties in the area were also raided by police.

Detectives continue to hunt 25-year-old Arthur Collins, the boyfriend of reality TV star Ferne McCann, over the attack.

Police say he should not be approached by members of the public if seen.

Two other men are also wanted for questioning, and CCTV images of the pair are currently being reviewed by investigators.

Twenty people suffered burns during the assault at around 1.10am on Monday, April 17.

Two men, aged 24 and 29, were transferred to a specialist burns hospital in Essex. They remain there in a serious but stable condition, police say.

Officers believe a dispute erupted between two groups of people developed before the substance, which is yet to be identified, was sprayed.

A 21-year-old man was arrested on suspicion of GBH on Friday.

He remains in custody at a north London police station.

A 24-year-old man was later arrested in north London, also on suspicion of GBH.

Detective Inspector Lee McCullough from Hackney CID, leading the investigation, said: "This investigation continues to move at great pace and the net is closing in on those we believe to be responsible.

"My team continue to act on a number of leads to bring in those wanted for questioning in relation to this awful incident.”
