A US man is facing a jail term after he attacked another man with his anger management homework.

Justin Boudin, 27, was on his way to an anger management class when he assaulted a 59-year-old woman at a bus stop.

He hit her in the face after she took out a phone to call the police when he started shouting at her.

When a 63-year-old man tried to stop him, Boudin hit him with a blue folder, which fell on the ground, and ran off.

Police who investigated the assault, in St Paul, Minnesota, tracked him down through the folder which officers said included his anger management homework.

Boudin has appeared in court where he pleaded guilty to assault, reports the Pioneer Press.

The Ramsey County Attorney's Office say he can expect to face at least 120 days in jail and probation.
