London's Metropolitan police did not immediately release the 15-year-old's and 16-year-old's names but said they were arrested on suspicion of robbery and grievous bodily harm. Officers at the scene said a corrosive substance was thrown onto a man whose facial injuries have been described as "life changing".
The attacks have sparked calls for tougher and more consistent sentences for those found guilty of acid attacks. One of the men took his vehicle and the other drove away on the moped they arrived on.
There have been over 120 attacks in London so far this year, with the frequency of the attacks leading to the city being dubbed the acid attack capital. At least two of those attacked were drivers for food delivery services Deliveroo and UberEATS. This is not the case. After again spraying the liquid in a victim's face, the moped was stolen and both attackers fled.
One witness saw police dousing the victim with large bottles of water.
He was targeted in a suspected robbery last night (Thurs) during a series of five attacks by men on a moped across north London in just 72 minutes, which police believe are linked. "My family's scared. They were asking me to leave that job, but I love that job".
More than 400 acid or "corrosive substance" attacks were carried out in the six months before April 2017, according to figures from 39 police forces in England and Wales.
Proposals to ensure acid and other corrosive substances can be classed as risky weapons are among the changes included in the shake-up.
Around 15 minutes later, a 24-year-old male suffered life-changing injuries after acid was thrown in his face at Cazenove Road, N16 near junction with Upper Clapton Road.
At 10.49pm a man was reported to have had a corrosive substance thrown in his face by two men on a moped in Islington.

The Home Office said it will work with police and the Ministry of Justice to assess whether sentencing powers available to the courts are sufficient.
