The Office of the Prime Minister on St Clair Avenue was evacuated earlier today after a bomb threat was allegedly made.
Guardian Media reported that a worker found a bomb threat written on the mirror of the female washroom.
The Acting Deputy Permanent Secretary ordered the evacuation after learning of the threat, with workers mustered to the nearby Nelson Mandela Park.
The building was searched and declared safe around midday, with a police presence remaining in force around the building.
