AUGUSTA — Due to a serious threat against Maine Bureau of Motor Vehicle branch offices, potentially from an aggrieved customer, the 13 BMV branches around Maine will only be open to scheduled appointments for the remainder of Tuesday.

The state issued a news release shortly before noon on Tuesday. Additional details were not provided on the threat.

“As our enforcement division works to resolve the threat against branches and out of an abundance of caution, branch offices will only be open for previously-scheduled appointments for the rest of the day,” said Secretary of State Shenna Bellows. “Our branch office staff will continue to provide service to those customers until we’re able to reopen fully to the public.”
