An acid attack in east

Two groups of males were said to have engaged in an argument on Saturday at Stratford Centre near London's Olympic Stadium, leading to them spraying a toxic substance.

Police said they have arrested a 15-year-old male in connection to the incident.

They said the attack is not terror-related.

"The injuries sustained were not "life-threatening or life-changing", police said.

"We are working with the Home Office to explore possible restrictions around the sale of corrosive substances in conjunction with retailers and manufacturers."

Burger King employee Hossen, 28, said a local homeless man came into the fast food outlet "to wash acid off his face".

There were 431 acid attacks in London last year, 398 of which were carried out in Stratford's borough of Newham.
