A Met Police taskforce seized two knives after a stop and search in Lewisham Saturday (May 9).

In an update posted to Twitter, the Met Police's specialist 'taskforce unit' said the weapons were seized while on patrol in London's South-East Borough Command Unit (BCU).

One of the two knives seized was labelled "nasty" by a police spokesperson who pointed out it it's shape — disguised as a keyring.

"The first stop of the day ended up with an arrest for possession of offensive weapons on @MPSLewisham.

"One particular nasty blade was disgused as a keyring #Autobots #KnivesTakeLives," the Met spokesperson posted to Twitter.

The Met Police have rigorously defended the use of the controversial 'Stop and Search' policy, which allows police to stop and search anyone they have "reasonable grounds" to suspect is involved in a crime.

An analysis of Home Office statistics made by civil rights group Liberty in 2019 showed that black people in England and Wales were "40 times more likely than white people" to be stopped and searched, leading Liberty to describe the policy as a "recipe for discrimination".
