Touts help cops seize pounds 3m assets; CRIME.
Substantial hauls of drugs, stolen cars and cash have been recovered and more than 600 suspects arrested in the past eight months.
Assistant Chief Constable Drew Harris said: "At a local level we are getting a lot of information and we are turning that into results.
"These are all about local criminals who are a blight on the local society."
ACC Harris added informers - now referred to by police as Covert Human Intelligence Sources - may be paid.
But he insisted: "There are no criminals being protected because they are providing information, be it as the old expression as a tout or now as a CHIS."
