Collins told his trial he had been out celebrating the news of Ms McCann’s pregnancy, which they had announced to her family the previous day.CCTV showed him and co-defendant Andre Phoenix, 21, arriving at the club at about 9pm before getting into a confrontation with a group of men about four hours later. But the jury at London’s Wood Green Crown Court convicted him of five counts of grievous bodily harm with intent and nine counts of actual bodily harm last month.Judge Lucas ordered that as well as his 20-year prison term Collins, of Broxbourne, Herts, will additionally be subject to five further years on extended licence.He branded Collins “an accomplished and calculated liar” who had shown “not a shred of remorse”, telling him: “This was a despicable act.”You knew precisely what strong acid would do to human skin.”Having thrown the acid over the club you slunk away and hid in the rear and pretended to be nothing to do with the mayhem you had caused.”In my judgement it was deliberate and calculated and you were intent on causing really serious harm to your victims.”Twenty-two people reported injuries to the police after the acid attack at the club in Dalston, east London, on April 17, which was packed with bank holiday revellers. Collins, the father of Ms McCann’s baby daughter Sunday, had told his trial he did not know the bottle contained acid, believing it to contain a liquid date rape drug, which he had snatched from two men after overhearing them planning to spike a girl’s drink. The ex-boyfriend of reality TV-star Ferne McCann has been jailed for 20 years after carrying out a brutal acid attack in a packed nightclub.Arthur Collins, 25, hurled the corrosive substance over a crowd on the dancefloor at Mangle E8 in what Judge Noel Lucas said was “a despicable act”.Sixteen people suffered chemical burn injuries and three people were temporarily blinded – one of whom still suffers from blurred vision in one eye. Fourteen were the subject of charges.In court Judge Noel Lucas described it as “a deliberate and calculated attack” and laughed off Collins’ defence claims that he had little money – pointing to the fact he had had two Harley Street hair transplants.He said: “I am a bit surprised by that. I suspect it wasn’t paid for on the NHS, and I dare say it wasn’t cheap.”He then added: “Here I am told Mr Collins has no brass farthings to rub together, in effect, not withstanding his lease on a Mercedes jeep and two expensive hair transplants.“If I sound as if I am sceptical of the information I have been given, it is because I am. I don’t believe a word, frankly.” Want the best of The Telegraph direct to your email and WhatsApp? Sign up to our free twice-daily Front Page newsletter and new audio briefings.
