Police in the UK are keeping tabs on “thousands of people” who may be involved in terrorism, Scotland Yard’s head of counter-terrorism says.
Peter Clarke told a BBC Two documentary Al-Qaeda: Time to Talk? that his officers had to be focused on a “whole range of people”.
“Not just terrorists not just attackers but the people who might be tempted to support or encourage,” he said.
He recently described the intelligence picture in the UK as “very disturbing”.
