Quebec provincial police have arrested a man in connection with alleged threats against media magnate Pierre Karl Peladeau last Sunday on Facebook.
Police say the suspect did not resist when he was arrested at his home on Tuesday evening in Chambly, south of Montreal.
He was remanded in custody after being questioned by police and is expected to appear in court today in Longueuil.
There was no word on what charge might be laid.
Police have not identified the suspect.
The Facebook post in question reportedly began with the words, "'Please someone shoot PKP" and was quickly removed.
A poster who identified himself as Sosa El Gambino apologized on Twitter and to police via tweets.
Peladeau last week confirmed what many had been expecting — that he will seek the leadership of the Parti Quebecois.
The new party leader will be chosen in May 2015, with the next Quebec election to be held in September 2018.
