Security picked up player in middle of hand

Hi all,

There is a limp by me in the cutoff, a raise by the action button, and the sb action player raises to $50, I call, the button raises to $220, and the sb calls and right after I call the $220 security abruptly escorts the small blind out of the poker room (apparently he was banned), they don’t let us finish the hand and take his $220 in chips out of the pot. Before anyone can do anything the dealer puts out the flop. I ask the floor to be called at this point and floor was not aware the player was going to be picked up.

What’s the remedy?

Thanks,
DT
