Glendora police pursued a female driver suspected of drunken driving though the San Gabriel Valley Wednesday evening, boxing her in with their patrol cars on the freeway.
The suspect was cornered by pursuing police just east of the Buena Vista Street exit on the Foothill (210) Freeway in Duarte (map).
Glendora police Sgt. Scott Strong said the chase began after the suspect appeared drunk and was refused service at T. Phillip's Glendora, a bar and restaurant in town.
The woman -- Michelle Masterman, 50, of Glendora -- left the bar and got into her vehicle. An off-duty officer attempted to dissuade her from driving while drunk, Strong said, but Masterman set off in her car.
The off-duty officer called the department, and patrol cars followed Masterman in a "slow pursuit" through the suburb, Strong said.
When Masterman stopped at a light, an officer tried to get her out of the car but the doors were locked. The officer broke the car's window with his baton, but she sped off and onto the 210 Freeway, Strong said.
After allegedly weaving in and out of lanes at speeds of up to 90 mph, Masterman was forced to stop by rush-hour traffic in Duarte. That's where Glendora patrol cars and one California Highway Patrol car boxed her in, Strong said.
Masterman was being held on suspicion of driving while intoxicated and felony evasion of police, Strong said.
