There were some scary moments for people working at North Bay City Hall Friday afternoon. 

The place went into lockdown after a threat was made around 3 pm.

Police locked down the building, and while they allowed people to leave, no one else was allowed in. 

Mayor Al McDonald says they got a call from somewhere outside of the city about a bomb threat, with city hall as the target.

Ontario Provincial Police were dispatched to a home in another city where the call originated.

The all clear was given within an hour.
