The Coventry Police Department is sharing a story about how a man was saved from an overdose while officers were making an unrelated arrest.  Police say Samuel Jackson of Providence was arrested during a traffic stop on Thursday after a week-long narcotic investigation stemming from complaints about drug deals being made near the Coventry Greenway bike path.  During the arrest, an unrelated vehicle arrived on the scene, and the driver reportedly told police his passenger was overdosing on drugs.  Detectives administered four doses of Narcan to the victim, and were able to revive him, according to the Coventry PD.  He was taken to Kent Hospital and later released.
