How to evict tenant from co-working space

[Maggie Smigh]

We have a co-working space in San Jose, CA and run into a problem with a most likely mentally ill tenant. I do not have evidence of his illness but he keeps making claims that someone is entering his office, touching his items. 

We have 24/7 video surveillance of all public spaces and no one ever entered his space. Today he became violent and aggressive. We sent him the notice of the termination, but I am afraid he will not leave voluntarily.

Does anyone have experience of the eviction from shared offices and what are the steps to take in CA, San Jose? He also claims that he is disabled which I have no information on complications for this.

I hope that this forum can help with some answers.
