A man is behind bars after he allegedly assaulted his girlfriend for not smelling his armpit. Sara Bustilloz tells CBS 7 that Robinson Pinilla-Bolivar’s girlfriend claims that as she was washing dishes, Pinalla-Bolivar asked her to smell his armpit.

She says she said no, and then they got into argument. She explains he responded by hitting her on the back of the head with a closed fist, and then held a knife to her. She then says he fled the scene, and she called the police. On November 13, police arrested Pinilla-Bolivar at a traffic stop.

He is charged with aggravated assault. The man claims that he did not threaten her, and that he threw the knife into the sink because he was angry.
