Police need your help tracking down a hit and run suspect who allegedly assaulted two state troopers. It all started last night during a routine traffic stop. The driver sped away from the scene. At one point, he turned off the headlights and pulled over, only to ram a state police cruiser and take off -- before crashing into a utility pole. Police arrested a passenger, Raymond Horn of Dickson City on charges of tampering with evidence but the driver took off running. Police are searching for 30-year old Charles Thompson, who`s last known address is in Throop. If you have any information, contact state police at the Wyoming barracks.
