Less than a week after Mayor Matt Mahan announced a bold push to arrest homeless people who refuse help, disturbing videos show San Jose police officers beating and verbally taunting an elderly homeless man —  leading to a complaint from the local NAACP chapter.

A homeless man is in custody for indecent exposure and allegedly biting officers. Part of the altercation is captured on video. Advocates say police went too far. Now the incident is under investigation.

The incident happened as the city is rolling out its latest plans to keep people from living on the streets.
