On November 14, 2017, Collins was found guilty of carrying out an acid attack after a trial at Wood Green Crown Court in North London.
He was convicted of five counts of grievous bodily harm with intent, and nine counts of actual bodily harm against 14 people.
Collins threw acid across the packed dance floor at Mangle nightclub in Dalston, East London, during an Easter weekend night out in April 2017.
He had claimed he threw the substance by mistake after hearing a group of men plotting to spike a woman's drink.
The court heard that he picked up a container that he thought was a date rape drug and threw it away.
But a jury found him guilty of carrying out the acid attack that left clubbers in agony and sparked a panicked evacuation and a massive emergency response.
Collins' co-defendant, Andre Phoenix, 21, of Tottenham, North London, was acquitted of four counts of grievous bodily harm and two of actual bodily harm.
CCTV footage played in court showed Collins throwing a substance into the face of another man before scattering it over others.
Jailing Collins, with an additional five years on licence, Judge Noel Lucas QC said the then-25-year-old was "an accomplished and calculating liar" who had failed to demonstrate "the slightest remorse".

Can you imagine being out enjoying yourself and some evil clown starts throwing acid around and you get splattered with it?
I am trying to work out why this Ferne creature would have so much animosity towards an innocent victim who was doing something that was absolutely none of Ferne’s business!
