Queensland Police have revoked an emergency declaration issued in a suburban area south of Brisbane and are working to substantiate reports of an armed man.

Officers were called to a Maple Street address in Marsden at about 8:30am on Friday following reports a group of people were unloading a safe from a truck.

Police said an “armed person” was spotted by officers inside the residence, and while three people were able to exit, it was reported that one person remained inside with a firearm.

A Public Safety Preservation Act (PSPA) declaration was made at about 10am due to public safety concerns.

Police said this was revoked after 12:30pm once they gained access to the property and confirmed no-one was inside.

South-east region duty officer Inspector Laurie Shevlin said specialist and general duties police had worked to resolve the incident as quickly as possible.

The emergency declaration encompassed Oregan Street, Hickory Street, Chambers Flat Road, Bunya Street and Birch Street.

Residents of those areas were urged to remain indoors, while the public was asked to avoid the area.
