When minor league hockey fans began receiving a flurry of push notifications from the American Hockey League app on Wednesday, they may have been expecting off-season news about the Cleveland Monsters, Lehigh Valley Phantoms or Rockford IceHogs. Instead, for roughly 20 minutes, users were bombarded with bizarre alerts that demanded a $6,000 payment from a man named Stewart Zimmel.

“Stewart Zimmel. Since I have no way to contact you are you owe me nearly $6,000 I would ask you to contact me about payment,” one of the notifications read. “Also, I’m filing a workplace report against you for threatening to punch me in the throat nemours times.”

That message was sent to users in at least three separate alerts and quickly became a talking point among hockey fans on social media.

Other push notifications from the app read, “Stewart Zimmel threatened to punch Ian Bowman in the throat” and “Stewart Zimmel please pay the outstanding monies owed.”
