Washington Wizards basketball guard Gilbert Arenas has begun serving a 30-day sentence in a halfway house for bringing guns into the team locker room.
The director of Montgomery County Corrections, Arthur Wallenstein, says Arenas arrived at the Montgomery County Jail on Friday evening local time, where he will spend two days for medical screening and classification.
He will then be transferred to the county's Pre-Release Center, a halfway house.
Corrections officials in Montgomery County, adjacent to Washington DC, agreed to let him serve his sentence there, as part of an agreement with the US Bureau of Prisons.
Arenas pleaded guilty to a felony gun charge in January, and has been suspended until the end of the season by the NBA.
