Cleveland Cavaliers president of basketball operations Koby Altman was arrested Friday night. He was charged with operating a vehicle while impaired and committing a marked lanes violation, according to a report from Fox8.

Ohio State Highway Patrol said Altman was stopped by officers for the traffic violation just before 9 p.m., per the report. Officers reportedly suspected Altman of impairment during the stop and he was subsequently taken into custody.

Altman refused to take a breath test but was “respectful and cooperative” with troopers, according to the report.

The Cavaliers released a short statement Saturday morning, saying they were aware of an "incident” involving the executive and were gathering more information.

Altman turned 41 on Saturday. He was promoted to general manager of the Cavaliers in 2017. Last season he finished second in NBA Executive of the Year voting behind Monte McNair of the Sacramento Kings.

Hometown star LeBron James sent the Cavaliers into a substantial rebuild phase with his exit in 2018. Altman’s leadership landed him on ballots for the NBA award this year after Cleveland won 51 games and returned to the NBA playoffs for the first time in four years.
