Authorities said a man appeared to swallow narcotics as police approached his vehicle after leading them on a slow-speed chase through Emerald Hills.

The chase ended when his vehicle ran over a spike strip.

Police officers pulled the suspect out of his car and took him to a nearby hospital for minor injuries, said San Diego police Sgt. Ray Battrick. The driver will be arrested on suspicion of evading officers.

A resident on the 5300 block of Roswell Street called police around 12:15 p.m. Saturday to report that the suspect's vehicle was driving up and down the street for four hours, said San Diego police Officer Larry Adair. The caller was concerned that the driver of the vehicle was casing homes in that area for potential burglaries, Adair said.

Police officers spotted the vehicle and signaled for the driver to pull over when he started driving away from them, Battrick said. The suspect led police on a chase through neighborhoods in the Roswell Street and Geneva Avenue area.

Other officers tried to clear nearby streets of playing children and a stopped ice cream truck in case the pursuit headed that way, according to police dispatcher.

Authorities laid down a spike strip at Roswell Street and Melrose Avenue, Adair said. The suspect's vehicle ran over the spike strip and came to a stop at the 800 block of Winston Drive.

The suspect refused to get out of the stopped vehicle and officers saw him eat something that looked like narcotics, Battrick said.

Officers broke the car's driver-side and rear windows and pulled the suspect out of the car.

The suspect was taken to a nearby hospital with non-serious injuries he sustained as he was forced out of his vehicle, Battrick said.
