Police have identified the driver who fled a routine traffic stop in Southbury Saturday and say the passenger is still at large.  A Southbury officer tried to stop a car on Main Street South for not having a license plate on the front of it, and a registration check found it belonged to another vehicle. 

The driver, later determined to be 29-year old Gabriel Antonio Deleon of Waterbury, didn't stop and the occupants were seen tossing items out the window.  The items were later identified as heroin and crack cocaine. 

State Police helped to box the vehicle in, but both fled on foot.  A helicopter and police K9 were brought in to help with the search.  Deleon had a large amount of cash in small bills in his possession, and an active warrant for probation violation. 

Deleon was charged with engaging police in pursuit, resisting arrest, possession of a controlled substance, sale of narcotics, operating an unregistered motor vehicle, failure to display plates, driving without a license and improper use of a marker, license or registration.  He is scheduled to be arraigned today.
