A 16-year-old boy in the United Kingdom faces 15 charges in five acid attack cases the London police have been investigating since Thursday. The attacks took places over a span of 90 minutes in the city’s north and east. The accused’s identity has not been revealed as he is a minor.

The charges against him include grievous bodily harm, robbery, attempted robbery and possessing an item to “discharge a noxious substance” among others. He will appear before a juvenile court on Monday. Earlier on Saturday, the police had arrested a 15-year-old boy in connection with the attacks, but he was released on bail.

All five attacks were carried out against men on moped by a duo that was riding a similar vehicle. Two mopeds, among them one that belonged to an UberEats driver, were stolen. One of the victims sustained life-changing injuries, doctors said.
