Arthur Collins, the boyfriend of reality TV star Ferne McCann, has been charged in connection with the acid attack on a London nightclub that left two people partially blind and others disfigured.
The 24-year-old was arrested at an address in Rushden, Northamptonshire, on Saturday.
On Sunday he was charged with 14 counts of wounding with intent to do grievous bodily harm and one count of throwing corrosive fluid on a person with intent to cause GBH, Scotland Yard said.
Collins, of Broxbourne, Hertfordshire, is due to appear at Thames Magistrates Court later.
A second man, Andre Phoenix, 21, will appear at the same court charged with seven counts of wounding with intent to cause grievous bodily harm.
Twenty clubbers were doused with a corrosive substance during a night out at Mangle nightclub in Dalston on Easter Monday.
A 22-year-old woman and a 24-year-old man were both blinded in one eye and several other clubbers sustained burns.
A 33-year-old woman and a 24-year-old man were arrested and later released from custody.
Collins had been in a relationship with Ms McCann, best known for her appearances on The Only Way Is Essex and I'm A Celebrity ... Get Me Out Of Here!
