London acid attack: Two teenagers were arrested on suspicion of attacking several people with corrosive acid. One teenager 16-year-old boy was arrested in Kingsbury Road, north-west London, early on Friday, while the other 15-year-old was arrested in Stoke Newington several hours later.
The attacks began at 22:25 BST on Thursday in Hackney Road.
The two male suspects riding a moped targeted victims during a 72-minute spree.
The Metropolitan Police said one victim had been left with "life-changing" injuries after being doused on Thursday night in the east of the capital.
At the start of the rampage, a 32-year-old moped driver had been approached by the pair as he drove towards the Hackney Road junction with Queensbridge Road. The two male suspects then tossed the noxious substance into his face before one of them jumped on to his vehicle and drove away.
LONDON ACID ATTACK
At least five people were attacked in a span of two hour.The five attacks on Thursday night, which were reported to police over a 70-minute period, are the latest in a spike of incidents using corrosive liquids as weapons in robberies and gang-related violence in the British capital.
Met Commissioner Cressida Dick said the growing trend of victims being doused with corrosive liquids was concerning.
Ms Dick told LBC Thursday night's attacks were "completely barbaric".
"The acid can cause horrendous injuries," she said.
"The ones last night involved a series of robberies we believe are linked - I am glad to see we have arrested somebody."
A Met spokesman said one line of inquiry detectives would be pursuing was whether the attackers were targeting moped riders to steal their bikes.
Assaults involving corrosive substances have more than doubled in England since 2012, with the number of acid attacks in the capital showing the most dramatic rise in recent years.
The Met's own figures show there were 261 acid attacks in 2015, rising to 458 last year.
So far this year - excluding Thursday night - the Met has recorded 119 such attacks.
