Brooklyn blog crownheights.info reports that last Monday night, a 911 caller told police a man was sleeping in the lounge of a local synagogue and outreach center.
When they arrived, the man apparently resisted arrest. As seen in the video above, he was repeatedly punched and pepper-sprayed before finally being arrested. (He was later released on bail.)
A source told crownheights.info the man had permission to live at the center.
