A man accused of stabbing to death two people and injuring three more in London has a previous conviction for an “Islamist terrorism-related offense” — and was wearing an electronic monitoring bracelet when he carried out Friday’s attack, according to a report.

The man — who was shot dead after being wrestled to the ground by bystanders in what British police called a “terrorist incident” — has a criminal history that includes a conviction for that unspecified offense, according to the Telegraph.

The madman, whose name has not yet been released, was sprung from prison about a year ago after agreeing to electronic monitoring, per the report, which cites anonymous government sources.

He was in the area of the London Bridge because he was due to speak at an event at Fishmonger’s Hall, where he was scheduled to share his experience as a rehabilitated man, the Times reports.

He was also wearing a phony suicide belt, authorities said.
