"New York City Comptroller Brad Lander was detained inside a Lower Manhattan immigration court building Tuesday morning by masked federal agents as he attempted to escort a man from his court appearance there. "
This is actually what happened, not the headline. He tried to forcibly remove someone there for court. It's all a a show, to make the Trump administration look bad.
"From a court appearance" is referring to him escorting the man out after the court appearance, not evading the court.
