A Rhode Island man took his NFL fandom to a dangerous level after allegedly threatening to shoot up Gillette Stadium ahead of the NFL season kickoff. The fan was upset about the recent signing of star wide receiver Antonio Brown with the Super Bowl champion New England Patriots.

Tobias Gray, 44, was arrested Sunday by police in East Providence, Rhode Island, after a Facebook post was discovered of Gray threatening to attack Gillette Stadium before the Patriots' home opener against the Pittsburgh Steelers. Police were notified of the alleged threat by one of Gray’s friends on Facebook. He was promptly arrested on charges of making a terroristic threat and a previous warrant for domestic assault.

Gray appeared in court Monday wearing New York Giants apparel to face the charges, though he did not enter a plea. He waived extradition to Massachusetts where he is wanted by the Foxboro Police Department for the threat as well. Charges were also amended Monday to include threatening a public official after reportedly making threats to a police officer while being processed.

“Just like everybody else, he was reacting as a fan,” said Gray’s lawyer Stefanie DiMaio Larivee on Monday. “Nothing that was said was ever meant to be in any seriousness.”

The original post was deleted by Gray reportedly before his arrest, though snapshots of it began appearing online.

Gray wrote in the alleged post: "I don't ever really post too many things so you know this is real since the Patriots signed Antonio Brown, I'm going to pull a white boys school shooting at Foxboro. You might as well just hand them the ring right now."

Brown signed Saturday after the Oakland Raiders announced he had been released after a controversy-filled offseason. The incidents included Brown complaining about his helmet, calling a member of the Raiders organization a racial slur and suffering frostbites from a cryo-chamber.
