DALLAS - The CEO of a Dallas-based website linked to prostitution and sex trafficking has been arrested, Texas Attorney General Ken Paxton announced Thursday.

The CEO of a website called Backpage.com was arrested at Houston's Bush Intercontinental Airport around 2 p.m. Thursday. He was returning from Amsterdam, where the company also has offices.

Paxton said authorities in California had been investigating Carl Ferrer for three years and brought information to officials in Texas several months ago.

“Initially he’ll face charges in California for pimping and other associated crimes, but Texas will have its own investigation,” Paxton said.

Ferrer was arrested on pimping charges from California. Late Thursday afternoon, Texas investigators were executing a search warrant at Backpage's offices at the corner of Oak Lawn and Maple Avenues in Dallas.

Paxton didn’t detail any future charges, but said the Texas investigation is not over.

“Backpage is the single largest advertiser of adult escort services,” Paxton said. The company “advertises sex acts for money,” and earns millions of dollars in advertising profits annually, he added.

The attorney general said both adults and children were exploited for financial gain.
