Washington Wizards star Gilbert Arenas is currently the subject of an NBA investigation over firearms he possibly stored in his locker in the past.

According to ESPN, the NBA confirmed the rumors, but said the container was locked and stored without any ammunition.

After the team found out, they notified the league and local authorities since it violated NBA rules.

The Wizards and Arenas say they "are cooperating fully with law enforcement during its review of this matter and will have no further comment at this time," according to the Wizards' statement.

The team's spokesman Scott Hall didn't divulge any details about when or where, but told the Washington Times on Christmas Eve (December 24) that the incident in question happened about two weeks ago.

"It happened like December 10th. Right after my daughter was born," Arenas said. "I decided I didn't want the guns in my house and around the kids anymore, so I took them to my lock box at Verizon Center. Then like a week later, I turned them over to team security and told them to hand them over to the police, because I don't want them anymore. I wouldn't have brought them to D.C. had I known the rules. After my daughter was born, I was just like, I don't need these anymore."

Arenas recently welcomed his third child, Hamiley Penny, earlier this month. His first daughter, Izela, turned 4 on Thursday.

While the NBA allows its players to legally possess firearms, it prohibits them being brought to league facilities or when traveling on any league-related business.

"We're aware of the situation and are working to gain a full understanding of the facts and relevant legal issues," the NBA said in a release.

This isn't the first time a player violated these gun rules. In 2006, Los Angeles Clippers guard Sebastian Telfair was suspended for two games and fined an undisclosed amount after a loaded handgun -- registered to his girlfriend -- was found in his pillowcase aboard the team's plane when he was with Portland.

According to the Washington Post, Arenas has not been charged with a crime yet.

At press time, it was unclear if the league will take any action regarding the incident.
