The victims, a woman in her 40’s and a man is his 20’s, were discharged from the hospital after treatment, the statement said.

On Friday, British police arrested two teenagers after five acid attacks on moped riders in less than 90 minutes across east London, which left several people with facial burns.

Metropolitan Police Commissioner Cressida Dick said the number of acid attacks appeared to have risen in the capital, though they remained relatively rare.
