Allegedly! The New York Post’s Peter Vescey and Ken K. Li claim Wizards G Gilbert Arenas and teammate Jarvis Crittenton threatened each other with handguns in their Verizon Center locker room on Christmas Eve, said incident occurring after the NBA began an investigation into Arena’s firearms possession.

The duel in DC — unprecedented in sports history — was sparked when Critten ton became enraged at the veteran guard for refusing to make good on a gambling debt, a source said.

“I’m not your punk!” Crittenton shouted at Arenas, according to a league source close to the Wizards.

That prompted Arenas to draw on Crittenton, who then also grabbed for a gun, league security sources said.

A playground pal of Crittenton’s from Atlanta, Kendrick “Bookie Ball” Long, confirmed the locker-room standoff and said he learned of it directly from the third-year player out of Georgia Tech.

“He [Arenas] was f- – -ing with him; he [Crittenton] was just defending himself!” declared Long, who said the dispute was over money but would not elaborate.

Quizzed by the Washington Post’s Michael Lee why he’d feel compelled to bring guns to his place of work,  Arenas replied “I’m a bank robber. I like to rob banks.” Probably not the sort of respone David Stern was hoping for,  and it should be pointed out this accusation of welshing on a debt is not the first time Gilbert’s been charged with an ethical lapse.
