HALIFAX -- Halifax police have ruled out a connection between a gun found on a public bus and the reported sighting of a man possibly carrying a concealed weapon.

A 25-year-old man was arrested and an unloaded, sawed-off shotgun was recovered from a bus on Thursday, hours after police received a report of someone walking along a downtown street with what appeared to be a rifle wrapped in black fabric.

Police say they've determined the incidents are not related and their investigation is ongoing.

The man was taken into custody without incident after police say he allegedly left a gun on the bus and walked down Argyle Street.

Justin Crathorne appeared in provincial court today on multiple charges, including possession of a weapon for a dangerous purpose and carrying a concealed weapon.

He was remanded into custody and his case was adjourned until Nov. 6.

Police say there were no threats made to anyone and no shots were fired.
