officers have this morning, Thursday, executed two search warrants in the borough and arrested one man after utilising the latest hi-tech camera technology in an effort to rid their ward of drugs. Over the last week officers from Haringey have been patrolling the borough with a unique thermal imaging camera that can accurately identify properties being used to cultivate cannabis. Being used for the first time within the Met police the hand-held camera is able to detect extreme heat emissions from houses. Properties where cannabis is being grown will release up to ten times the amount of heat as an average family home. I wonder if civil liberty groups will query intrusive surveillence?
