The leader of La Luz del Mundo, a church with its headquarters in Mexico that claims to have more than one million followers worldwide, was charged Tuesday in Los Angeles with more than a dozen sex crimes, including allegations that he forced children to have sex and made them pose naked for photos, the authorities in California said.

The leader, Naasón Joaquín García, 50, was arrested Monday at Los Angeles International Airport, according to the California attorney general’s office. Mr. García is considered by La Luz del Mundo, which has locations in the Los Angeles area, to be an apostle of Jesus Christ.

Three other people affiliated with the organization were also charged Tuesday, according to the attorney general’s office. One of the people was also arrested at the Los Angeles airport, another was arrested elsewhere in Los Angeles County, and the authorities are still seeking the arrest of the fourth person, the attorney general’s office said.

In a 19-page complaint filed in Los Angeles County Superior Court on Tuesday, prosecutors said there were four victims, three of whom were children. One child and a woman were raped, prosecutors said in the complaint. Mr. García is also accused of human trafficking and forcing children to perform oral sex.
