It is reported that two men on a moped carried out five acid attacks during a spree across London which lasted less than 90 minutes, police said.
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.
The assaults appeared to be linked and two involved victims having their mopeds stolen, they added.
A male teenager was later arrested on suspicion of grievous bodily harm and robbery and has been taken to an east London police station
An eyewitness said he heard a victim, who he believed was a delivery driver, "screaming in pain". One victim suffered "life-changing injuries".
Police are looking at whether moped theft was the motive for the attacks.
Officers said they were linking the attacks and young boys aged 15 and 16 have been arrested on suspicion of robbery and causing grievous bodily harm.
Delivery services Deliveroo and UberEATS have confirmed two of the victims were couriers working for the firms
The acid attacks happened as there are some concerns about the number of assaults involving corrosive substances in London.
According to BBC, Hackney resident Jon Moody said he was watching TV when he heard screaming and ran to the window.
"I heard a high-pitched scream but thought it was the boys playing football... I heard more shouting and ran to my window," he said.
"I could see a man in serious distress, he was screaming in pain.
"There were only two police officers with the victim, they took out two large water canisters and poured it over him."
He said he believed the victim was a delivery driver and about 20 fellow delivery drivers turned up at the scene.
The Hackney Gazette last week reported many delivery drivers are refusing to work in some areas after 21:30 BST because of robbery fears.
