(CNN) -- Federal prosecutors revealed a photograph Thursday that they say show an Amish man attacking another Amish man by attempting to forcibly cut his beard.

The photo was submitted as evidence in the trial of 16 Amish men and women charged with federal hate crimes in connection with last year's beard-cutting attacks in rural eastern Ohio. The trial started Monday at federal court in Cleveland with jury selection.

To the Amish, a beard is a significant symbol of faith and manhood.

The photo was recovered from a disposable camera that was used to document the attacks, which prosecutors say were ordered by Samuel Mullet Sr., the Amish leader of a breakaway sect and one of the 16 defendants. Prosecutors did not identify the attacker or the victim in the photo in their court filings.

If convicted, Mullet faces 20 years in prison, according to CNN affiliate WOIO in Cleveland.

According to witnesses cited in a federal affidavit, Mullet "forced extreme punishments" on anyone in his community who defied him, "including forcing members to sleep for days at a time in a chicken coop on his property." In addition, the affidavit alleges that, as the bishop of his Amish clan in Bergholz, Ohio, Mullet had "acts of sexual intimacy" with married women as part of "counseling" to "cleanse them of the devil."

CNN has sought a response from Mullet's attorney, Edward Bryan. Bryan has disputed the prosecution's characterization of his client, according to The Cleveland Plain Dealer.

"They're trying to create this perception he's something he's not," Bryan told the newspaper. "He's not a wacky cult leader. He's a decent, hardworking, caring man."
