WATERVILLE (AP) — Waterville police are investigating a bank robbery in which the thief “made a threat of violence” to the teller.

Police say a man walked into the TD Bank branch on Main Street just before 6 p.m. Thursday and handed the teller a note that contained the threat.

The teller handed over an undisclosed amount of cash and the robber fled on foot toward Appleton Street.

The suspect was described as a heavyset man about 6-feet tall, wearing a dark jacket, a black face mask and baseball cap and gloves.

Police did not disclose the nature of the threat or the amount of money stolen.

The suspect escaped despite a heavy response that included a dog unit.
