BETHEL – Police on Friday arrested a Main Street woman and charged her with robbing a KeyBank employee at gunpoint on Thursday.

Nancy Plante, 30, was charged with robbery after Maine State Police troopers and detectives questioned her at the Bethel police station Friday night.

Plante lives in an apartment at 52 Main St. The bank she is accused of robbing is at 96 Main St.

Plante is accused of brandishing a gun to threaten KeyBank Assistant Manager Marjorie Osgood who arrived to open the business about 8:30 a.m. Thursday.

The robber, hiding her face with a scarf and a cap, followed Osgood into the bank foyer and demanded money. Osgood took money out of her own account with an ATM card and gave it to the woman, police said.

The victim described the woman who robbed her as nervous and desperate for money. No shots were fired.

When it was over, the suspect fled on foot toward High Street and for the remainder of the day, remained at large. The robber kept the town on edge as a school and some businesses locked up while police arrived to investigate.

State police sent a team of eight detectives, including the Evidence Response Team and its crime lab van and troopers to assist Bethel police and the Oxford County Sheriff’s Office with the investigation.

State Police spokesman Stephen McCausland did not have specific information about what led police to Plante as a suspect. Footage from a bank surveillance camera provided images of the woman who robbed the bank employee.

Police did not say whether any of the stolen money or the gun used in the heist had been recovered during the investigation.

Plante was taken to the Oxford County Jail on Friday night where she was expected to be held at least until she makes a court appearance next week.
