A 38-year-old woman was arrested Friday afternoon after she allegedly threatened to commit suicide, then led police on a high-speed chase before a police dispatcher persuaded her to give herself up.

The Cumberland County Sheriff’s Office said Angela Harrison threatened to commit suicide in Greene, where she lives. Police were alerted to look for her, and she was seen on Route 115 in Windham shortly after 3 p.m.

When she stopped and a deputy approached her car, the sheriff’s office said, she rolled up her window and started to drive off. The deputy smashed the driver’s side window and used pepper spray, but Harrison sped away.

With the deputy chasing her, Harrison continued on Route 115, passing cars and reaching speeds of 85 mph, the sheriff’s office said. Deputies rolled out a spike mat on Route 115 in Gray, but Harrison missed it and then went onto the Maine Turnpike northbound.

The sheriff’s office said that Harrison dialed 911 on her cellphone and spoke to a state police dispatcher in Gray, who persuaded her to pull over and surrender.

Harrison was charged with eluding a police officer, driving to endanger, criminal speeding, reckless conduct and failing to submit to arrest. She was being held in the Cumberland County Jail on Friday night on $400 cash bail. She is scheduled to be arraigned on May 13.
