'Mass acid attack' at Stratford station leaves at least six injured and 15-year-old boy arrested

Six people have been injured in a mass acid attack in London.

Shocked witnesses saw victims lying on the floor "in agony" after the incident at Stratford shopping centre and train station.

One victim was shouting: "I can't see, I can't see" as others fled the scene in panic.

A 15-year-old boy has been arrested and police said the incident is not terrorism-related.

It is believed the acid was sprayed after an "altercation" between two groups of young men.

The London Ambulance Service said: "We treated six patients in total and took three to London hospitals."

Police said none of the injuries is life-threatening or expected to be life-changing.

Video and pictures of the scene of the horrific scene appeared on social media.

Pictures posted on Facebook show a man with his shirt removed being tended to by emergency services outside the shopping centre. The extent of his injuries are not clear.

Another witness, an assistant manager at Burger King, said one victim ran into the fast food restaurant to wash 'acid' off his face.

The 28-year-old told the BBC: "There were cuts around his eyes and he was trying to chuck water into them."

In a statement, a spokesman for the Metropolitan Police said: "Police were called just before 8pm on Saturday, 23 September to the area around Stratford Shopping Centre to reports of a group of males spraying what is believed to be a noxious substance.
