A Tucson man suspected of kidnapping his ex-girlfriend was arrested Friday after a high-speed, cross-town police chase.

Ozziel Ramirez, 20, was taken into custody at about 1:30 p.m. Friday near Ryan Airfield about 10 miles southwest of Tucson. Ramirez's 23-year-old ex-girlfriend was in the car and uninjured, authorities said.

Tucson police arrested him Friday evening on three counts of domestic violence - kidnapping, endangerment and unlawful imprisonment. He is also facing a count of felony fleeing, authorities said.

U.S. marshals and the U.S. Border Patrol assisted in detaining Ramirez, Tucson police said.

Ramirez is suspected of kidnapping his ex-girlfriend at 8 p.m. Thursday by implying that he had a gun. The woman had been riding in the passenger seat of a vehicle that pulled into the Quik Mart at 5642 S. Alvernon Way near East Drexel Road, said Sgt. Chris Widmer, spokesman for the Tucson Police Department.

According to a witness, Ramirez "blocked their vehicle in with his vehicle, preventing them from leaving the parking lot," Widmer said. Ramirez then got out of his 2006 Audi sedan "with a rag over his hand and implied he had a gun. He ordered (the victim) out of the vehicle and into his."
