On Friday, visitors to backpage.com, a website for classified ads, were greeted with a message notifying them that the site had been seized by several US federal agencies, including the FBI, Postal Inspection Service, and IRS Criminal Investigation Division.

The note also said the investigation was being aided by the Department of Justice’s Child Exploitation and Obscenity Section, as well as US attorney general offices in Arizona and California. The notice was posted to the site several hours after the Arizona home of its co-founder, Michael Lacey, was raided.
