Three DA investigators in the hallway? Just arrested a guy who had a warrant, showed up for court and was taken into custody

I was outside Courtroom 1. Could not figure out why three DA investigators were just hanging out. They got a warrant, he showed up for court and was taken into custody because he allegedly violated his restraining order.

He saw bailiffs and tried to exit in the opposite direction, did not work for him out for him today. Inmate is Timothy Ziegler.
