Wellington Street between Elgin Street and Bronson Street was closed on Saturday afternoon in what police described as an “active police operation”.
Metcalfe Street is closed between Albert Street and Slater Street.
Heavily armed officers are parked on the roads leading to Wellington, with vehicles and police tape blocking access.
Police are urging citizens to stay away from the area.
At least some employees working in the parliamentary precinct received an email saying that an ongoing operation is underway to deal with a possible threat.
“There has been a SHELTER order on the site given for the enclosure, this does not involve movements inside or outside our buildings. Parliament Hill has been evacuated.”
