The latest altercation involving Thomas Bruso began when a younger man on the bus began yelling at Bruso, who calls himself "Tom Slick," "Vietnam Tom" and "Epic Beard Man."
Bruso was taken to the John George Psychiatric Pavilion for an evaluation after he struck the male passenger several times with his fist and continued to rant about the incident, Alameda County Sheriff's spokesman Sgt. J.D. Nelson said.
A video of the brawl captured by a college student, Iyanna Washington, showed the two men speaking to each from across the aisle near the center or rear of the bus.
The younger man then ordered the 6-foot-1, 280-pound Bruso away from him, to the front of the bus.
Bruso angrily stalked to the front, followed by the younger man who continued to yell at Bruso. The exchange continued with the goading of other passengers until finally the younger man struck him. Bruso stood up and returned the blows, beating the man until he fell to the floor with a bloody nose.
AC Transit spokesman Clarence Johnson said the younger man's nose was broken. No one was arrested.
"He (expletive) hit me.
Last year, Bruso was involved in another incident, also captured on video and widely circulated on YouTube and other Web sites.
At an Aug. 3, 2009, A's ballgame, Oakland police officers used a stun gun on Bruso because he refused repeated requests to leave the ballpark. He hadn't been drinking but had brought alcohol into the stadium, police spokesman Jeff Thomason said at the time. When Bruso refused to leave, Coliseum security asked Oakland police officers working the game to eject him. Three officers verbally tried several times to get Bruso to leave, but he refused.
The situation quickly escalated after Bruso made a rude gesture at one of the two officers. They then placed a handcuff on Bruso's left wrist. A third officer arrived with a Taser, stunning the man in the left shoulder blade while another officer was placing the other cuff on Bruso's right wrist. The third officer applied the Taser on Bruso again, this time near the middle of his back, which caused Bruso to fall forward into an aisle. He was charged with resisting arrest and taken to a hospital for a psychiatric evaluation.
