The comedian who openly celebrated Kobe Bryant's death is triggering a wave of threats aimed at the comedy club where he was supposed to perform ... forcing cancellations.
Law enforcement sources tell TMZ ... Ari Shaffir was scheduled to do stand-up at the New York Comedy Club Tuesday night at 9:15 PM, but the club was forced to call cops after getting multiple phoned-in threats.
Our sources say someone called threatening to shoot up the place because a comedian scheduled to perform there made a vile joke about Kobe.
