Thiago Silva Arrest -- Wife's Alleged Boyfriend; I Need a Break From Fighting

The guy who owns the jiu-jitsu studio where Thiago Silva allegedly whipped out a gun and threatened to shoot a bunch of people has shut his doors ... but only for a couple days ... in the wake of the insane events that occurred this week.

According to the police report, not only did the UFC star pull up to the studio and threaten to kill his wife and her alleged new boyfriend ... he also threatened to shoot everyone inside the studio.

Which is why the people who run the place decided to shut it down for a few days ... posting a sign on the door Saturday to let patrons know they'd resume business on Monday.
