Scotland Yard is deploying covert officers at “toxic” police stations and in special units to catch sex predators and prevent another David Carrick or Wayne Couzens scandal.
James Harman, a senior Met commander, revealed the undercover operation as the force announced a UK-first plan to re-vet staff that could root out 30 to 50 “bad apples” a month by stripping them of their licence to operate.
