 Police say the detective tried to pull over a vehicle in the parking lot of the Royal Farms on South DuPont Highway around 5.30 on Tuesday afternoon, but the Yukon sped away during the pursuit. Detectives saw the driver throw an object out of the Yukon while driving in a reckless manner on several streets and roads. Eventually, the vehicle stopped. Detectives deployed stop sticks and found a cigarette pack that was thrown from the Yukon. They say it contained powdered cocaine and heroin.
