A lawsuit stemming from 1991 involving Jon Hamm has surfaced this week, revealing he was accused of brutal fraternity hazing at University of Texas-Austin the previous year.

The lawsuit, filed by then-Sigma Nu fraternity pledge, Mark Allen Sanders, accuses the Mad Men star and others of lighting him on fire and other violent acts.

The AP obtained a copy of the lawsuit 24 years after it was filed, which resulted in a hazing charge and a dismissed assault charge. He was ordered to probation but was never convicted, which is called deferred adjudication under the state’s law.

Sanders claimed in the lawsuit that Hamm was involved in the violent incident "till the very end,” which allegedly included him getting beaten up, dragged across the room with a hammer and his pants being lit on fire.

Hamm became "mad, I mean really mad” when Sanders failed to recite his tasks.

The incident was widely covered by local outlets at the time, but Hamm wasn’t famous. He just completed 30 days in rehab for an addiction to alcohol.
