Connecticut police arrested Olander, a 21-year-old senior forward, during the weekend after he failed field sobriety tests, The Hartford Courant reported Monday.
He was charged with operating a motor vehicle under the influence of alcohol/drugs, operating an unregistered motor vehicle and driving without a license.
Olander was suspended from the team for "violating team rules," a university spokesman said Monday afternoon.
He was arrested in Panama City, Fla., in March when he refused to leave private property after being asked to leave by police.
Olander played 26 games for UConn last season but missed the final game because of a broken foot. Last year he averaged 4.3 points, 3.7 rebounds and 0.9 blocks.
