The National Portrait Gallery in Parkes has been reopened, ACT police have confirmed.
ACT police said they received a report of a phone call threat to the shop within the gallery at 12.25pm on Tuesday.
The building was evacuated but nothing suspicious was found.
ACT police are trying to identify the caller.
"ACT Policing reminds the community that it is an offence to make false threats and those who commit this offence can expect to face court where heavy penalties may be imposed," a spokesperson said.
The incident follows an evacuation at the Woden centre on Monday.
Officers were notified of a phone call about an alleged "threat to a store" at about 1.10pm.
It is not clear whether the two incidents are linked.
More to come.
