under arrest
Arrested by the police.
I thought: should I be worried? I was under arrest. In a town where I'd never been before. Apparently for murder. But I knew two things. First, they couldn't prove something had happened if it hadn't happened. And second, I hadn't killed anybody. Not in their town, and not for a long time, anyway. Lee Child
All people look better under arrest. John Waters
