MILWAUKEE (AP) A Milwaukee officer involved in the stun gun arrest of Bucks' player Sterling Brown has been fired because of social media posts mocking the incident, the city's police chief said Thursday.

Police Chief Alfonso Morales said the firing decision was not tied to anything Erik Andrade did when Brown was arrested, but explained that the social media posts compromised the officer's ability to testify in other cases. Morales spoke about the case at a Marquette University event.

Brown sued the police department in June and accused officers of using excessive force and targeting him because he's black. A group of officers swarmed on him at a Walgreens parking lot because he didn't immediately remove his hands from his pockets. Brown was standing with the officers waiting for a citation for parking in a disabled spot early on Jan. 26, but never appeared to threaten police before or during his arrest, according to police body camera videos.
