Art Taylor, 18, swallowed the small bag but was arrested on several other charges after police pulled him over on Union Avenue at 8:35 p.m., police spokesman Lt. Ron Brandolini said.
Members of the street crimes unit patrolling Franklin Street saw a car turn onto Pearl Street without signaling. They stopped the car on nearby Union Avenue, but when they spoke to Taylor, he refused to give them his license or registration, Brandolini said.
"He made a quick movement to the center console, and there was small baggie with a white powder in it," Brandolini said. "He immediately made a movement to put it in his mouth."
An officer tried to stop him, but Taylor kept pushing his arm away. The officers dragged Taylor from the car, and he started fighting with them in the middle of the road.
By the time officers handcuffed him, Taylor had swallowed the bag, Brandolini said.
