Authorities say the 43-year-old man was arraigned Thursday in connection with alleged threats against Cmdr. Ian Lafreniere.
Montreal police spokesman Danny Richer says it was a tip from citizens who noticed alleged Internet threats against Lafreniere that led to Wednesday's arrest.
Police say the charges have nothing to do with the case of a woman who was charged with criminal harassment last week after she posted a photo online of graffiti showing Lafreniere with a bullet in his head.
Jennifer Pawluck was released under conditions and ordered to appear before a judge at a later date.
