A robbery at a 7-Eleven early Tuesday morning led to a wild police chase in Medford, authorities say.

News 12 was told that a suspect pulled a gun and took cash from a worker – then entered a waiting Jeep with two other men inside, and drove off.

A state trooper saw the vehicle run a red light and pulled it over.

Two of the men were arrested and a third fled on foot.

About two hours later, the suspect was located and tracked down with the help of a police chopper and a K-9 unit.
