London Bridge attackers began plans two weeks before strike

Ringleader Khuram Butt was under MI5 investigation, inquest hears

The London Bridge terrorists started preparing their atrocity more than two weeks before they struck, while the ringleader Khuram Butt was under MI5 investigation, an inquest has heard.

Three 12-inch knives used in the attack on 3 June 2017 were bought 19 days earlier from an east London Lidl supermarket. During the attack a rented van ran over people on London Bridge, killing two, before three terrorists sprinted out to stab to death six people.
