The Church of Scientology leader, David Miscavige, has allegedly been accused of hiring spies to follow his elderly father.

According to a police report, Miscavige spent $10,000 a week on spies over an 18-month period. The son feared his father, Ronald Miscavige, would circulate negative material around about the organization, according to People Magazine.

The two detectives supposedly hired to follow around his father placed a GPS tracking device on his car, photographed his activities, eavesdropped on his conversations and rummaged through his garbage.

The alleged surveillance surfaced when a private investigator, Dwayne S. Powell, was arrested in 2013 after police answered a call about suspicious activity. Powell was found with four handguns, two rifles, a stun gun, a silencer and hundreds of rounds of ammunition. He was arrested on suspicion of obstruction.

Powell claims that he and his 21-year-old son were hired by the Church of Scientology to perform surveillance on Ronald Miscavige.

“Powell stated that if Ron was doing anything that was deemed to be not in the best interest of the church, he would report to his contact and the church would send people from L.A. to intervene and speak with Ron to correct his behaviors,” according to a police report by Detective Nicholas Pye.

“He explained that Ron and his younger wife, Becky, left the church and David is worried that they will divulge details about the church’s activities and that their job was to know who Ron talked to, emailed with, met with, where he went, what he did, etc.”

Mr. Miscavige’s attorney, Michael Lee Hertzberg, stated that his client had never even heard of Powell. “Mr. Miscavige does not know Mr. Powell, has never heard of Mr. Powell, has never met Mr. Powell, has never spoken to Mr. Powell, never hired Mr. Powell and never directed any investigations by Mr. Powell,” he wrote in a statement sent to PEOPLE.
