A 22-year-old woman injured in an acid attack at a London club has been blinded in her left eye, police have confirmed.
Detectives hunting the boyfriend of The Only Way Is Essex star Ferne McCann in connection with the incident have urged him “to hand himself in”.
Police have released CCTV images of Arthur Collins, 25, and have urged members of the public not to approach him.
Twenty people were injured when the substance was sprayed during an argument at Mangle E8 nightclub in Dalston, east London.
Detective Inspector Lee McCullough, from Hackney CID, said: “I am continuing to appeal to Arthur Collins to hand himself in so that we can talk to him about the incident in the nightclub.
“I would also urge anyone who knows of his whereabouts to contact police.
“We now have 20 people suffering from the effects of an acidic substance being sprayed in a confined space in a busy nightclub. All have burn-related injuries.
“The noxious substance used has not yet been confirmed but samples retrieved from the scene have been sent for analysis.
“If you were there and saw anyone involved inside or leaving the nightclub, please get in touch.”
Two male clubbers, aged 24 and 29, remain in a serious but stable condition in a specialist burns hospital in Essex.
Police believe the substance was sprayed directly into the faces of the men after an argument broke out in the early hours of Monday.
Two other men are also wanted for questioning in connection with the incident.
Collins, a scaffolder from Hertfordshire, had recently appeared on the front cover of OK! Magazine alongside McCann.
The pair, who have been dating for nine months, told the magazine they were planning on moving in together and had even spoken about getting married.
McCann has appealed to her boyfriend “to co-operate fully with the police and attend a police station immediately”.
Her TOWIE co-stars stars, Jamie Reed, Jade Lewis and Chloe Meadows, were among those at the bank holiday event.
Celebrity Big Brother star and ex-Premier League footballer Jamie O’Hara has condemned the “sick” attack which injured his cousin Sadie Wright.
Around 600 people had been at the late-night gig and about 400 were still in the building at the time of the attack.
Police say there is no evidence to suggest it was gang-related.
Officers have carried out three arrest warrants at addresses in Hertfordshire. A 33-year-old woman was arrested on suspicion of firearms offences following the raids.
