The boyfriend of The Only Way Is Essex star Ferne McCann is being hunted by police in connection with a nightclub acid attack that injured 20 people. Police have released CCTV images of Arthur Collins on the night of the attack in Mangle E8 nightclub in Dalston, east London. Police have urged members of the public not to approach Collins, and have raided an address in Hertfordshire in connection with the incident.

Two male clubbers, aged 24 and 29, are in a serious but stable condition in a specialist burns hospital in Essex. Police believe the “noxious substance” was sprayed directly into the faces of the two men after an argument broke out in the early hours of Monday. Police are yet to confirm exactly what the substance is, but London Fire Brigade spokeswoman said: “It was identified by a PH paper test as a strong acidic substance.”

Collins, a 25-year-old scaffolder, 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.
