A Portland woman accused of robbing a bank then holding police at bay during a six-hour standoff Sunday, remains in the hospital under guard while waiting to be cleared for transport to the Cumberland County Jail.

Jill Polley, 34, of 1808 Forest Ave. is charged with bank robbery, endangering the welfare of a child and creating a police standoff. At one point she appeared to be using her 5-month-old son as a shield while threatening to shoot members of Portland’s special reaction team, police said.

Polley is accused of robbing Norway Savings Bank on Congress Street Saturday, threatening that she had a gun and demanding money. She was identified by witnesses who saw security video distributed by police.

When police responded to her basement apartment Sunday morning, Polley refused to let officers inside and at times, threatened to hurt herself, police said.

When police were unable to contact her Sunday afternoon, special reaction team members smashed open the back door and confronted her there, police said. Polley held her child in front of her, threatened to shoot the team members and refused to show officers her hands, police said.

Eventually, a police negotiator persuaded her to put down the baby and to lie on the floor, at which point she was arrested and the baby was carried to safety. Police did not find a gun.

Polley has been arrested in the past on drug charges, police said. An ambulance was summoned after she was arrested because she seemed disoriented and was having trouble staying awake, police said. She was taken to Maine Medical Center where she remained this afternoon.
