Suspect who fought San Jose mayor’s security detail identified

Around the 55-second mark in the video, the pedestrian appears to land a right-hand punch to the security detail’s head.

In the beginning of the video, a person is seen walking by Mahan’s right shoulder before approaching the mayor’s protective detail. The two are heard in a verbal exchange as Mahan tells the pedestrian he is in the middle of an interview.

The pedestrian then tells the security detail, who is a San Jose Police Department officer, to “mind your (explicit) business.” “I was going to do what the (explicit) I was going to do right before you walked up to me,” he said to the security guard.

Soon after, the altercation went from verbal to physical. The pedestrian is heard telling the officer that he will smack him.

The two struggled for a few minutes before bystanders helped the mayor’s security detail. The pedestrian was eventually detained by SJPD officers.
