RCMP in Campbellton continue to investigation a suspicious package incident that resulted in the evacuation of a building on Aberdeen Street on Wednesday.
Police were called when an envelope containing a powder substance was found inside the building, which houses the local library and several offices, including the constituency office of Progressive Conservative MLA Greg Davis.
Tests showed the powder was not dangerous and a woman who had been quarantined as a precaution was released, said Const. Jullie Marsh-Rogers.
But investigators are withholding information about the nature of the powder and other details of the case in the northern city.
"The RCMP is not confirming details surrounding the delivery of the envelope, including which office is was sent to at this time," said Marsh-Rogers.
"However, we are certainly asking about information about the incident. Anyone with information is asked to contact the Campbellton RCMP."
If the investigation reveals any evidence of wrongdoing, charges are possible, said Marsh-Rogers.
No one was injured in the incident, which began at about 9:30 a.m.
The building, located at 19 Aberdeen St., was reopened at about 6 p.m., after a special unit from Halifax that deals with bombs and hazardous materials gave the all clear.
