FAIRFIELD - A police officer suffered minor injuries early Monday after a woman he was questioning began to drive away. Police say the woman later told officers she wanted to finish drinking her beer before she surrendered.

Officer Brad Wolfe was "noticeably injured," but he refused medical treatment following the 3 a.m. incident, said Lt. Kevin Haddix.

Police arrested Christina L. Willis, 36, of Fairfield, after a half-hour chase.

Officer Wolfe heard a disturbance at the Capri Motel and stopped to investigate. Police allege Ms. Willis began moving her 1990 Toyota Camry, dragging Officer Wolfe about 30 feet before he broke free of the vehicle, Lt. Haddix said.

Other officers began following Ms. Willis. The Butler County Sheriff's Office succeeded in stopping her car at Interstate 75 and Union Centre Boulevard by using "stop-sticks," a device that punctures tires.

Ms. Willis was being held in the Butler County Jail on charges of felonious assault on a police officer, fleeing and eluding, reckless operation and operating a motor vehicle while intoxicated.

Officer Wolfe smelled alcohol on Ms. Willis, but she refused a breath test, Lt. Haddix said.

Ms. Willis is scheduled to appear today in Fairfield Municipal Court.
