An armed teenager wearing an ankle monitor was arrested Sunday after leading law enforcement officers on a high-speed chase through multiple counties after beginning in the Midlands, the Sumter County Sheriff’s Department said.

Although the 16-year-old driver was charged with failure to stop for blue light and possession of a stolen vehicle, there’s an ongoing search for a passenger in the SUV who ran away, the sheriff’s office said in a news release.

The incident began at about 8:15 a.m. when the sheriff’s department was told about a Hyundai Santa Fe slowly driving down Brabham Road, according to the release. That’s in the Dalzell area.

A search of the SUV’s license plate showed it was from Kingstree, and deputies said it was soon heading east toward Interstate 95.

The chase ended when a Florence County Sheriff’s Office deputy deployed a stop stick and the SUV crashed into a ditch, according to the release. Both the driver and a passenger ran from the SUV, and a black handgun was visible in the driver’s waistband, the Sumter County Sheriff’s Office said.

A Sumter County police dog tracked the pair as they ran into a field and woods, while bloodhounds from the Florence County Sheriff’s Office were also called to the scene, according to the release.
