TEWKSBURY (CBS) – A woman taking money out of an ATM in Tewksbury on Monday was robbed at gunpoint.

The drive-up ATM at the Stoneham Savings Bank on Main Street is a popular spot on the side of the bank itself.

The robbery happened on the Memorial Day holiday at around 5 o’clock.

“He basically demanded her money,” says Deputy Police Chief John Voto. “After a few minutes of going through her pocket book, he realized she didn’t have anymore and then let her leave the situation.”

Voto says the suspect took the woman’s keys while he went through her purse. He ended up getting away with $30.

Police are reviewing surveillance video of the suspect, who is described as six feet tall, wearing a gray hooded sweatshirt, a blue bandanna over his face and blue latex gloves. Police sent out a reverse 911 call to warn the community.

Police say they have some good leads.
