Redbridge Police will choose locations to conduct searches under the Terrorism Act in a new Met initiative

The revised tactics, which state that controversial Section 44 powers should only be used in pre-identified significant places, were introduced yesterday across the capital.

Sites chosen will include iconic and particularly crowded locations, although officers will still have the power to stop anyone they suspect of being involved in terrorist activities under Section 43 of the 2000 Act.

The move is the latest review of how Section 44 powers are being used across London after officers came under fire for "overusing" the Act.

In May, the Guardian reported that stop and search powers were used by Redbridge officers on an average of 17 times a day.

After a successful three-month pilot scheme in Southwark, Brent, Tower Hamlets and Newham, each borough will now compile a list of the places where the powers can be used.

Commander Simon Bray from Territorial Policing said: “Stop and search under the Terrorism Act 2000 remains an important tactic in our counter terrorism strategies.

“It can disrupt and deter terrorist activities by creating a hostile environment for terrorists as well as providing visible reassurance to the public.

“The review of Section 44 and the tactics being launched are designed to ensure we continue to protect Londoners while addressing the concerns that have been raised. “
