Former Scientologist Leah Remini left the religion in 2013. She has subsequently written a book called Troublemaker and now is hosting a documentary series on A & E Leah Remini: Scientology and the Aftermath.
She and another former Scientologist Mike Rinder, interviewed three others who had left the church, including leader David Miscavige own father Ron. All of them told tales of being physically abused by Miscavige, who according to them would attack without provocation. According to USA Today, Jeff Hawkins one of the ex-Scientologists interviewed said,
“…he jumps up on the table, launches himself at me, knocks me back against the partition wall, starts hammering my face, knocks me down on the floor. I was scratched up. My shirt was ripped off.”
The church has vociferously denied all of the allegations.
