ACTON — An Acton town official had to be arrested Monday afternoon after he made verbal threats toward officers from the York County Sheriff’s Office.

Chief Deputy William L. King Jr. said his officers arrested 51-year-old Donald Ouellette – the town’s Assistant Rescue Chief – and charged him with criminal threatening.

Ouellette had gotten into a heated argument with the rescue chief, King said. During the confrontation, Ouellette allegedly went to his car and removed an item that may have been a gun – it was wrapped up.

When police officers spoke with Ouellette they gave him a written order to stay away from the fire station. Ouellette allegedly said he planned to attend a meeting of the Rescue Department board on Thursday, despite the written order to stay away.

At that point, he made threatening remarks toward the officers, who arrested him, according to police.

King said that at some point Monday night Ouellette submitted his letter of resignation to town officials.

Ouellette posted $100 bail and was released from the York County Jail. He is scheduled to appear in Springvale District Court on Sept. 24.
