A second boy, 16, has been arrested after an acid attack which left a pizza delivery driver in a life-threatening condition.
The boy is being held on suspicion of grievous bodily harm in relation to the attack in Walthamstow, east London.
The fast-food driver, who police say had a corrosive substance repeatedly thrown into his face, is likely to lose sight in both eyes.
The 32-year-old driver was approached by two men on a moped in Walpole Road at around 6pm on Thursday.
After attempting to steal the victim's moped, a noxious substance was thrown at him, causing severe injuries to his eyes and face.
