A man on his way to anger management class became angry and struck a woman, authorities said.

Justin John Boudin, 27, pleaded guilty Friday to fifth-degree assault in Ramsey County District Court and can expect to face a sentence for time served in jail, at least 120 days, and probation when he is sentenced May 5, the county attorney's office said.

According to a criminal complaint, Boudin was waiting at a bus stop on August 29 when he accosted a 59-year-old woman and others.

"Why don't you show me some respect?" he allegedly yelled at the woman.

When she took out a cellphone to call police, he hit her in the face, according to the complaint. When a 63-year-old man tried to stop Boudin, Boudin hit him with a blue folder - which fell on the ground - and fled.
