The National Portrait Gallery has been evacuated and police have closed roads in the area after a possible threat has been made.
An ACT Policing spokesperson said officers were responding to an incident at the gallery.
“The building has been evacuated as a precaution and people are asked to avoid the area,” the spokesperson said.
The incident follows the evacuation of the Westfield Shopping Centre at Woden yesterday after ACT Policing received a report of a phone call relating to a threat to a store at about 1:10 pm.
The shopping centre was evacuated as a precaution. The store was searched and nothing suspicious was identified.
An investigation into the incident is ongoing.
It is unclear if the two incidents are linked.
