LOS ANGELES--Federal agents raided a Philippines-based church in Los Angeles Wednesday in a human trafficking investigation that led to arrests of three church leaders in what prosecutors said was a decades-long scheme to trick followers into becoming fundraisers and arrange sham marriages to keep them in the United States.

The local leader of the Kingdom of Jesus Christ church was arrested on immigration fraud charges in the early morning bust along with a worker who confiscated passports of the victims of the scheme and another who handled finances, the U.S. attorney’s office said.

Workers who managed to escape from the church told the FBI that they had been sent across the United States to work long hours soliciting donations year-round for the church’s charity and were beaten and psychologically abused if they didn’t make daily quotas, according to an affidavit filed in support of the charges. Some described having to live in cars at truck stops.

The immigrants essentially became full-time workers, sometimes referred to as “miracle workers,” in a crusade to raise money for the nonprofit Children’s Joy Foundation USA, which was supposed to benefit poor children in their homeland. But the complaint said most of the money raised was used to finance church operations and the lavish lifestyle of church leader Apollo Quiboloy.

The church claims a membership of 6 million people and backed the 2016 candidacy of President Rodrigo Duterte, a close friend of Quiboloy. Duterte has used the group’s radio and TV program in southern Davao city to express his views on issues way back when he was mayor of the southern port city.

Quiboloy claims to be “the appointed son of God” and in October last year claimed he stopped a major earthquake from hitting the southern Philippines.

Between 2014 and the middle of last year, $20 million (2 billion yen) was sent back to the church in the Philippines, the FBI said.

“Most of these funds appear to derive from street-level solicitation,” according to the affidavit by FBI Special Agent Anne Wetzel. “Little to no money solicited appears to benefit impoverished or in-need children.”

Calls to the church for comment were not immediately answered.

Guia Cabactulan, 59, the top church official in the United States, was arrested in Van Nuys with Marissa Duenas, 41, who allegedly handled fraudulent immigration documents, prosecutors said. Amanda Estopare, 48, who allegedly enforced fundraising quotas, was arrested in Virginia.

Cabactulan and Duenas are expected to make initial court appearances Thursday in U.S. District Court in Santa Ana, said Thom Mrozek, a spokesman for the U.S. attorney in Los Angeles. Estopare was ordered held after a hearing in Norfolk, Virginia, and expected back in court Monday.

Investigators documented 82 sham marriages over a 20-year period between top fundraisers and church members who were U.S. citizens.

In addition to raiding the church’s Van Nuys compound, agents were conducting searches at other Los Angeles-area locations and at two places in Hawaii linked to the church.

Two years ago, a leader of a Hawaii branch of the church was arrested smuggling cash onto a private plane in Honolulu bound for the Philippines with Quiboloy on board, according to court records.

Investigators said Felina Salinas declared she was carrying $40,000. But investigators said they discovered $335,000 and $9,000 in Australian currency stuffed in socks in her carry-on suitcase, according to documents filed in U.S. District Court in Honolulu. U.S. law requires that travelers declare currency in excess of $10,000.

Prosecutors said a witness saw Salinas and Quiboloy order church members to smuggle hundreds of thousands of dollars in black socks packed in suitcases from California to the Philippines in 2013 and 2014.

A defense lawyer questioned the credibility of the witness in the Hawaii case.

“I have a woman who says she saw $100,000 go from California to the Philippines, then she said it was two or three million,” attorney Michael Green said, according to Hawaii News Now. “She says it was put in socks. They must have parishioners with size 18 feet because the socks must have been really big.”
