RCMP in Campbellton have evacuated a building on Aberdeen Street and one person is in quarantine after a suspicious package was discovered this morning.

The package was an envelope containing a powder substance.

Officers responded to 19 Aberdeen St., which houses the local library and several offices, including the constituency office of Progressive Conservative MLA Greg Davis and New Brunswick Legal Aid Services, at about 9:30 a.m.

The envelope was in one of the offices, but police won't say which one.

Local roads in the northern city remain open, said Const. Jullie Rogers-Marsh.

"There is no danger to those living in the area," she said.

The woman who found the envelope was quarantined as a precaution.

No police officers went inside the building.

A police cruiser remains on the scene and there is yellow caution tape blocking the doors of the building, located between Adam and Minto streets.

A special unit from Halifax that deals with bombs and hazardous materials has been called in and the investigation is ongoing, said Rogers-Marsh.

A notice on the Campbellton Centennial Library's website says the library is closed "due to unforeseen circumstances."
