The Merrimack County Sheriff’s Department has opened an investigation into the Allenstown Highway Department.

On Oct. 8, Sheriff Scott Hilliard said detectives are examining an allegation of “misuse of town property,” including property owned by the Highway Department, but would not say what the property in question was.

However, “I don’t think we’re talking about thousands of dollars,” Hilliard said.

Allenstown Police Chief Shaun Mulholland confirmed his department began the investigation but turned it over to the sheriff’s department.

“We took it on for obvious reasons,” Hilliard said. “It involves town workers.”

Hilliard said detectives questioned highway workers the week of Oct. 8. No charges have been filed.

A call to the Highway Department for comment was not returned.
