One of the victims suffered life-changing injuries in the attacks on Thursday night carried out by two people riding around north London on a single moped.
In at least two of the incidents, mopeds were stolen from the victims, and in a third, a robbery was involved.
Over the next hour and a half, three other men in the Hackney area of London and one in neighbouring Islington had corrosive material thrown at them, police said.
One of the victims of the spate of acid attacks has said he does not feel safe in London because of what happened.
Around 40 minutes later, at around 11.05pm, another victim was attacked by two men on a moped on Shoreditch High Street, having liquid thrown in his face.
The latest assaults come after several other high-profile attacks, including one in which a man is accused of throwing acid at an aspiring model and her cousin as they sat in their vehicle.
U.K. Interior Minister Amber Rudd announced Sunday that officials are considering new measures to confront the rise of acid attacks, including urging courts to impose life sentences in certain cases and requiring age checks for those buying corrosive substances. Within 15 minutes, they appeared to have struck again, launching their corrosive load at a man on Cazenove Road and causing "life-changing" facial injuries. Food delivery rider Jabed Hussain, 32, had his moped stolen and his face sprayed with liquid.
Mukhtar, 37, said there was no other reason for the attack than Islamophobia, especially in the wake of the recent terror attacks in Manchester and London. Both teenagers are now being held in police custody. He was later taken to an east London hospital by a female passerby. The growing trend of acid attacks also has the government considering ways to increase the penalties for the crime. They stole his moped and made off.
She said: "We will seek to ensure everyone working in the criminal justice system, from police officers to prosecutors, has the powers they need to punish severely those who commit these appalling crimes".
