Police were searching the Vermont Capitol building and evacuating employees, media reports said earlier on Friday, adding that nearby streets were blocked off.
Some state government buildings have been on lockdown in Vermont's Capitol complex in Montpelier after a report of a gunman as well, according to the governor's office.
State Buildings Commissioner Christopher Cole said, cited by AP, that a member of the public had reported that someone was seen going into the building that houses the Vermont Department of Taxes at 133 State Street with what appeared to be a long gun.
The state department of human resources issued earlier a statement saying that "the situation is well under control and not a danger", without elaborating.
According to the latest governor’s office statement, cited by Reuters, a lockdown of Vermont state office buildings in Montpelier was lifted later on Friday after a police search found no gunman or weapons.
