London club "acid attack" injures 12

At least 12 people had suffered burns from a suspected "strong acid" attack as about 600 revelers were evacuated from an east London club, local police said Monday.

Police officers said they believe that a man had thrown acid at two men after a dispute between two groups inside the nightclub.

The incident occurred at about 1:10 a.m. as 10 were taken to hospital to be treated.

Two men in their 20s remain in a serious but stable condition in hospital, the Metropolitan Police said.

A spokesperson with London Fire Bridge said that a "strong acidic unknown corrosive substance" was thrown inside the venue, Mangle E8 in Dalston.

"It was identified by a PH paper test as a strong acidic substance," he said.

A Scotland Yard spokesman said earlier the injured were treated for minor burns and their injuries are not life-threatening.

Police are still investigating into the cause of the incident but ruled out that the attack was gang related.

The attack came amid the Easter holiday.
