In yet another attack in London, two teens riding on a moped in east London threw acid on individuals in five separate attacks.
Two men on a moped carried out the attacks over 90 minutes in Hackney, Stoke Newington and Islington on Thursday night.
One of the victims suffered “life-changing injuries”.
The assaults happened amid increasing concern about the sharp rise in acid attacks in London.
One suspect, described as a male in his teens has been arrested on suspicion of grievous bodily harm and robbery. He is currently in custody at an east London police station.
Police are treating all five incidents, which took place within around 70 minutes, as linked. Four of the attacks happened in the London borough of Hackey, and one other in Islington.
Police said the latest attacks were linked and are questioning the teenager at an east London police station on suspicion of grievous bodily harm and robbery.
The attacks began at 22:25 BST on Thursday in Hackney Road.
A 32-year-old man on a moped was left with facial injuries after another moped, with two male riders, pulled up alongside him and threw a corrosive substance in his face.
One of the men stole his moped and the other drove away on the vehicle they arrived on.
The Met said it was awaiting an update on the extent of the victim’s injuries. Inquiries are ongoing.
