She is sitting on his back in the street: a woman performs a citizen's arrest on a man

A woman, dressed in casual blue jeans and a red sweater, is seated on a man's back, who is lying face down on a city street, his hands behind his head. The woman has her right hand gripping the man's left wrist in a determined manner, signaling a citizen's arrest. The surrounding streets are lined with tall, gray concrete buildings, and there are a few bystanders watching with surprised expressions. The sky overhead is clear, hinting at a calm day.
