All 12 of the people arrested by officers investigating the London Bridge terror attack have been released without charge, Reuters reported.

Seven women and five men were arrested in Barking on Sunday following Saturday's atrocity which left seven dead and 48 injured. 

In Britain's third Islamist attack in as many months, three men on Saturday rammed a van into pedestrians on London Bridge before running into the Borough Market area, where they slit throats and stabbed people indiscriminately. All three attackers were shot dead by police, who made at least a dozen arrests in east London on Sunday and carried out further raids on Monday.
