The US police have launched a massive investigation into life under the Fundamentalist Church of Jesus Christ of Latter-Day Saints.
More than 400 children, mostly girls in pioneer dresses, were swept into state custody in what authorities described Monday as the largest child-welfare operation in Texas history.
The daylong raid on the sprawling compound built by now-jailed polygamist leader Warren Jeffs was sparked by a 16-year-old girl's call to authorities that she was being abused and that girls as young as 14 and 15 were being forced into marriages with much older men.
Authorities are looking for evidence that the girl, who allegedly gave birth at 15, was married to a 50-year-old, and for records related to other mothers aged 17 and younger. Even with their parents' permission, Texas law forbids girls younger than 16 to marry.
Dressed in home-sewn, ankle-length dresses with their hair pinned up in braids, some 133 women left the Yearning for Zion Ranch of their own volition along with the children.
State troopers were holding an unknown number of men in the compound until investigators finished executing a house-to-house search of the ranch, which includes a cheese-making plant, a cement plant and several large housing units. They initially had difficulty getting access to the 80-foot white limestone temple that rises out of the brown scrub, but were searching it Monday.
"In my opinion, this is the largest endeavor we've ever been involved in in the state of Texas," said Children's Protective Services spokesman Marleigh Meisner, who said the agency was also involved in the 1993 siege of the Branch Davidian compound in Waco.
