A city man is jailed without bail following a routine traffic stop on Jamestown's southside for allegedly being in possession of more than 300 doses of Heroin.  City Police Captain Bob Samuelson says a patrol car pulled over the vehicle on Newton Avenue shortly before 2 p.m. Wedneday for failing to signal a turn.  Samuelson says officers walked up to the car... and, a back-seat passenger... 37 year-old Larry Johnson.  He says Johnson was caught after running through several back-yards... and, found with the packaged Heroin in his possession.  Samuelson says it totalled about 87 grams of Heroin... a "significant amount" of the drug for a vehicle and traffic stop.  He says it's believed that Johnson was going somewhere to sell the drugs.  However... they don't know where.  He says Johnson was arraigned in City Court on charges of third-degree criminal possession of a controlled substance... and, obstructing governmental administration.  He was then sent to the county lock-up... pending further court action.  The driver... who was not identified... also faces several vehicle and traffic laws.
