WASHINGTON (AP) — One NBA coach says the investigation into Gilbert Arenas and guns is "a scary thing for the NBA."

Miami's Erik Spoelstra (SPOHL-strah) says his team is closely watching developments regarding the Washington Wizards and their point guard.

Law enforcement authorities are investigating the presence of firearms in the Wizards locker room shortly before Christmas.

An official within the league says he was briefed by those reviewing the matter. He says the review included a dispute over card playing, gambling debts and a heated discussion between Arenas and another player.

The official spoke to The Associated Press on condition of anonymity Saturday because he is not an authorized spokesman for the team or the league.
