Six people have been injured in a mass acid attack in the area of a shopping centre in east London.
They were hurt following reports that a group of people were spraying a noxious substance near Westfield, Stratford, police said.
Police said a number of people have been reported injured at different locations within the area.
Emergency services were pictured at the nearby Stratford Centre, while footage from the scene shows paramedics treating an injured person at Stratford Tube station.
Officers have arrested a man on suspicion of causing grievous bodily harm.
Hossen, 28, a Burger King assistant manager, said he saw a victim and his friend run into the fast food outlet’s bathroom ‘to wash acid off his face’.
He said: ‘There were cuts around his eyes and he was trying to chuck water into them.’
Witness Zak Abdi told the Mirror: ‘It didn’t hit just one person, it hit a crowd of people. One guy had been hit in the face, he kept shouting ‘I can’t see, I can’t see, I can’t see’.
‘I think he has lost his vision. He kept shouting, it was a scary moment for everyone.’
There are unconfirmed reports that an argument broke out between a group of people in the area.
Some witnesses took to social media to describe the scene, with Kirsty Austin writing: ‘Too scared to leave the station I think if I heard right…
the guy on the floor had acid thrown at him.’
A spokesman for the Met Police said the incident is not being treated as terror-related.
A statement said: ‘Police were called just before 8pm on Saturday September 23 to the area around Stratford Shopping Centre to reports of a group of males spraying what is believed to be a noxious substance.
