A teenager has been arrested after two men on a moped carried out five acids attacks in London that lasted less than 90 minutes, police say.

One victim was left with "life-changing" injuries after being doused late on Thursday night in the east of the capital, the Metropolitan Police said.

The assaults appeared to be linked and two involved victims having their mopeds stolen.

A male teenager has been arrested on suspicion of grievous bodily harm and robbery.

One of the victims, a 32-year-old man on a moped, suffered injuries to his face when two male riders on another moped threw a corrosive substance in his face.

One of the men then stole the victim's vehicle and the other continued to drive away in the moped they arrived on.

Less than an hour later, a corrosive substance was reportedly thrown in a person's face on Shoreditch High Street.

The victim was taken to hospital but their injuries are not believed to be life-threatening.

Minutes after this attack, police were called to a robbery in Cazenove Rode, Stoke Newington, where a corrosive substance had also been thrown.

In a fourth incident in Clapton, a man on a moped had liquid sprayed in his face by two men also on a moped, before his vehicle was stolen.

The victim was taken to hospital.

Police investigations are ongoing.
