BLOOMINGTON, Ind. (AP) — The son of Boston Celtics great Larry Bird has been arrested after police say he tried to run over his ex-girlfriend with a car.

Twenty-one-year-old Conner Anthony Bird faces preliminary charges in Bloomington, Ind., including intimidation with a deadly weapon, battery with injury and possession of marijuana.

Indiana University police arrested Bird on Sunday morning but a jail officer says Bird is no longer in custody.

Authorities say his ex-girlfriend told a police officer that Bird threw a cellphone at her and drove his car at her during an argument.

A police report says IU police arrested Bird — who is a student — after tracking down his vehicle.
