Seven people have been arrested by British police in the investigation into an attacker, who killed three people and injured about 40 before being shot to death by police, Britain’s most senior counter-terrorism officer said on Thursday.
Mark Rowley said the latest figures were that there were four dead including the attacker and 29 people being treated in hospital, seven of whom were in a critical condition.
Police had said late on Wednesday that the death toll was four, including the attacker.
Rowley said police had searched addresses in London, Birmingham and other parts of the country in their investigation.
“It is still our belief … that this attacker acted alone and was inspired by international terrorism. At this stage we have no specific information about further threats to the public,” Rowley said.
He said there was a mix of nationalities among the dead but gave no details.
The victims were a policeman who was stabbed and two members of the public, a woman in her mid-40s and a man in his mid-50s.
The fourth dead was the assailant.
