London police are investigating four attacks in east London, involving corrosive substances being thrown in people's faces.
BBC reported that the attackers were on a scooter as they threw the substance at their victims.
All four attacks occurred in Hackney and Stoke Newington in London's east on Thursday night, local time.
Four victims were taken to hospital, with one suffering "life-changing injuries", the BBC reported.
It reported that a 32-year-old man on a scooter suffered facial injuries after two male riders pulled up alongside him and doused him in a corrosive substance.
One of the attackers stole the man's scooter while the other fled on the scooter he arrived on.
Footage posted on social media appears to show paramedics treating a man following the attack.
They pour water into his eyes and ask him where the incident happened. "Just here," he says, pointing to a nearby intersection.
"We need to try and get water in your eyes, keep your eyes open," the paramedic says.
The incidents are believed to be linked. No arrests have been made.
More to come.
The story, London police investigating four acid attacks in 90 minutes: reports, first appeared on the Sydney Morning Herald.
