Art-activism group Special Patrol Group are thought to be behind a series of anti-police posters that have been appearing in London.
The posters, designed by anarchist magazine STRIKE!, first started appearing in 2014, but have recently made a comeback.
In an especially bold move, one of the posters was even put up outside New Scotland Yard headquarters.
A Met police spokesman told The Independent:
On Sunday, 2 August, officers were made aware of a poster, purporting to be from the MPS, being displayed inside advertising space at a bus stop in Lewisham High Street, SE13.Advertisement
The owners of the advertising space were contacted and removed the poster.
A number of similar posters purporting to be from the MPS were removed from locations in Coldharbour Lane, Lambeth on Sunday, 2 August. These posters were not displayed inside advertising space.Advertisement
