LONDON, Sept 23 (Reuters) - Six people were believed to have been injured on Saturday after a group of males reportedly sprayed a noxious substance in an area around a large shopping center in east London, police said.
The incident near the Westfield shopping center in Stratford was not being treated as terror-related, a police spokesman said.
"A number of people have been reported injured at different locations - believed to be six people. We await further details," London's Metropolitan Police said in a statement.
