Wow! An agent who uses physical violence on another agent should not be practicing real estate in my estimation. Yes, I definitely suggest that you speak with your Broker about it and file a formal complaint with your local REALTOR board as this agent needs to learn that this type of behavior is totally unacceptable. The Board takes these type of issues seriously and will determine how this agent should be reprimanded.
I once filed a complaint with my local board about another agent's conduct and won my case as she had violated one of the standards of practice with NAR's REALTORS Code of Ethics.
Good luck to you!

My gooness! I would contact the DRE and post a ethics complaint about this agent. Furthermore, I would make your broker aware of the situation as well. I have seen some pathetic behavior by unscrupulous individuals, but it has never been physical.
Im sorry to hear this and I do hope you take it all the way to the removal of this persons license to practice Real Estate.
