The team investigating one of the 2017 London Bridge attackers was not told he had been reported to an anti-terror hotline, an inquest has heard.
Khuram Butt’s brother-in-law had reported his increasing radicalisation in September 2015.
In the same month MI5 assessed Butt as wanting to stage a terror attack but lacking the ability to do so.
Eight people were killed in the attack he carried out with two other men.
