Daniel Montalvo, a former Scientologist, is suing the Church and it's offshoot, Sea Org, for damages exceeding $25k for Breach of Fiduciary Duty and Negligence.

In the lawsuit, exclusively obtained by RadarOnline.com, Montalvo alleges Sea Org engaged in slave labor practices - forcing him to work over 100 hours per week when he was a minor for between $25-$50 per week.

He also alleges negligence, claiming that he only went to school one day a week while under the organization's care, and that he lost a finger while working for the Church.

Hollywood superstar Tom Cruise requested the Church of Scientology custom-build him a luxury SUV so he could accommodate his then-pregnant wife, Katie Holmes, according to a former high-ranking staff member.

John Brosseau, a 30-year member who has since left the church, has claimed he worked on two motorcycles, an airport hangar and the lavish vehicle for the actor -- all while he was getting paid $50 a week while “supposed to be working for the betterment of mankind”.

The Scientology whistle-blower is speaking out for the first time, as it emerged the FBI had launched an investigation into the church for using free labor -- in part, according to former Scientologists, to service the demands of its celebrity icon Cruise.

Hollywood superstar Tom Cruise had a custom-built luxury bus made for him using Scientology “slave labor,” according to the church’s former Inspector General, Mark Rathbun, who also claims to have top-secret internal e-mails proving so.

According to one email Rathbun says was written by Yvonne Gonzalves, the Director of Vehicles of the Sea Org branch, the super-secret organization within the Church which was responsible for building the trailer-style bus, staffers put in nearly 9,000 man hours into production of the vehicle.
