An unusual incident prompted an overnight evacuation of a building in St. Stephen early Saturday.
Shortly after 4 a.m., more than a dozen tenants were asked to leave their apartment on Schoodic Street.
The RCMP said what was believed to have been a flammable liquid was poured in the hallway of the building.
They said all residents were evacuated as a precaution and no one was hurt.
A 31-year-old man was arrested at the scene. He is being held in custody pending a court appearance.
The Canadian Red Cross has arranged lodging and meals for 14 people, including three children.
Officials say it could take several days of clean-up and ventilation before they are allowed to return home.
An investigation into the incident is ongoing. Anyone with information is asked to contact the St. Stephen RCMP.
