Officers with Redding's new neighborhood police unit have been going undercover to bust drug dealers. Wednesday night an undercover sting operation was done toward the south end of Hilltop Drive, prompted by tips from the Hilltop Business Owners Association. One arrest was made for sales of Methamphetamine. Police say that while they were staking out the scene they saw transients panhandling from shoppers and then using the money to buy drugs from the dealer. No names or exact locations have been made public by police because the unit is continuing the undercover operation.
