Police investigating Saturday night's terror attack in London say they know the identity of the three attackers who killed seven people and injured 48, BBC reports. 

The Met Police said their names would be released "as soon as operationally possible" as officers work to establish if they were part of a wider network.

They were shot by police after driving into pedestrians on London Bridge and stabbing people in Borough Market.

Officers searched two addresses in east London on Monday morning.

Police said a "number of people" had been detained following the raids, in Newham and Barking.
