Police Platform Patrols Cut Crime in London Underground

A massive experiment that deployed regular police patrols on platforms in the London Underground has shown that four 15-minute patrols a day in some of the capital's most crime-ridden stations reduced reported crime and disorder by 21%.

Researchers from Cambridge University's Institute of Criminology worked with the British Transport Police (BTP) to conduct the experiment across six months in 2011-2012. The findings have been published in the journal Criminology.
