Police Sgt. Timothy Gauerke says the department is investigating what happened and the officers' use of force.
Gauerke says officers contacted a man after seeing a vehicle parked across two handicapped parking spots while doing a business check at about 2 a.m. Gauerke did not say what led to the officers' use of force and it wasn't immediately known whether Brown was cited for anything.
Team spokesman Barry Baum said that the Bucks were "aware of the matter. We completely support Sterling and are confident that this will be resolved quickly."
Brown is averaging 3.5 points per game and 1.8 rebounds this season.
