Apparently, when 23-year-old UCLA student Mostafa Tabatabainejad didn't immediately vacate the building, security operatives returned with police officers to escort him from the premises. The Daily Bruin writes: "By this time the student had begun to walk toward the door with his backpack when an officer approached him and grabbed his arm, at which point the student told the officer to let him go. A second officer then approached the student as well.
During the unacceptable, disgusting, and unjustified act of tasering Tabatabainejad, the abusive and militant officers even threaten other students who try to rally to his cause in the end.
Warning: the videos below may be disturbing to some.
The LA Times has a story about it and it looks like the student will file suit. NBC News 4 covers it from an off-campus "safe zone" - yes the girl they talk to is afraid to go onto the campus with the video footage for fear of being questioned and possible detained.
