The Metropolitan Police said on Saturday (October 16) that the murder of British lawmaker David Amess in Essex on Friday (October 15) had been declared as a terrorist incident, with the investigation being led by its Terrorism Command.

Amess, 69, from Prime Minister Boris Johnson’s Conservative Party, was knifed repeatedly in the attack at about midday in the Belfairs Methodist Church in Leigh-on-Sea, east of London.

A 25-year-old man was arrested at the scene on suspicion of murder, and detectives said specialist counter-terrorism officers were leading the initial investigation. Politicians described the attack as an assault on democracy.
