The London attacker acted alone, therefore, no further threats to the public are expected, the national lead for Counter Terrorism Policing and the Acting Deputy Commissioner, Mark Rowley, said.
“It is still our belief - which continues to be born out by our investigation - that this attacker acted alone yesterday and was inspired by international terrorism," he said.
“To be explicit - at this stage, we have no specific information about further threats to the public. Clearly our investigation is ongoing and is focused on his motivation, his preparation and associates," he added, noting that they have searched six addresses - and made seven arrests.
He also added that according to the latest figures he has, there are currently four dead and 29 people were treated in hospital.
