MILWAUKEE — The longstanding effort by Milwaukee police to mend their relationship with black residents suffered another setback after the release of video showing officers using a stun gun on an NBA player over a parking dispute.

The body camera video is also the first major challenge for new Police Chief Alfonso Morales' goal of restoring trust in a department that has been besieged by excessive-force lawsuits in recent years.

The January video showed a group of officers swarming Bucks player Sterling Brown because he had his hands in his pockets and was asked to remove them. Within seconds, he was hit with a stun gun and lay on the ground groaning.

Morales says the officers who took part in the arrest were disciplined, but he did not say how.
