SAN FRANCISCO (AP) - Police say a man was arrested on suspicion
of driving under the influence after he shut down San Francisco's subway system for more than two hours after driving his SUV onto the underground tracks.

A spokesman says 40-year-old Scott Mitchell, of Sebastapol, Calif., is also charged with driving on train tracks and failure to obey a traffic sign.

No injuries were reported and Mitchell is expected to be cited and released.

Police say his vehicle entered a tunnel on Church Street shortly before 6 a.m. Thursday and traveled eastward almost to the Van Ness
Station. No trains were involved.

All underground train lines were shut down and resumed service by 8:15 a.m.

Some tracks were damaged, but crews will do repairs with trains moving slower through the affected area.
