London Bridge and Borough High Street, closed off to the public since the terror attack on Saturday (June 3) night, have reopened.
Metropolitan Police said in the early hours of Wednesday (June 7) morning that large part of the outer cordon of the crime scene has been lifted.
Roads to the east of Borough High Street have also reopened to the public, but Borough Market and a small surrounding area remain closed.
The opening of the roads came as police carried out a search warrant at an address in east London in the early hours of Wednesday (June 7).
Officers from the Met’s Counter Terrorism Command, supported by officers from the Territorial Support Group, entered the address in Ilford at around 1.30am.
A 30-year-old man was arrested on suspicion of the commission, preparation or instigation of terrorist acts (contrary to section 5 Terrorism Act 2006) and has been taken into custody at a south London police station under the Terrorism Act 2000.
A search of the address is ongoing.
The attack claimed the lives of seven people, and saw three suspects shot dead.
The force said that while formal identification is yet to take place, detectives believe him to be Youssef Zaghba.
Zaghba, joined former Transport for London (TfL) worker, Khuram Butt, 27, and Rachid Radouane, 30, both from Barking, in carrying out attack.
