Michael David Barrett was arrested Friday night as he arrived on a flight from Buffalo, N.Y., the FBI said. He faces federal charges of interstate stalking for taking the videos, trying to sell them to celebrity Web site TMZ and posting the videos online, the FBI said in a statement.
Several TV networks and newspapers aired brief clips or printed screen grabs from the videos in July.
Andrews thanked FBI agents and federal prosecutors for their work on the arrest and said she hoped the case will eventually help others who have been similarly victimized.
"For my part, I will make every effort to strengthen the laws on a State and Federal level to better protect victims of criminal stalking," she said in a statement early Saturday.
The charges against Barrett were filed in Los Angeles, where TMZ is based and where Andrews first became aware of the videos. She is identified in the federal complaint as E.A.
Andrews' attorney, Marshall Grossman, said he called her Friday night with news of the arrest. She was greatly relieved, he said.
"I think she's probably sleeping more soundly tonight than she has since these videos surfaced," Grossman said.
FBI agents said seven of the eight videos posted online were taken through a modified door peephole while the 31-year-old Andrews was alone and undressed in hotel rooms in Nashville, Tenn., in September 2008.
FBI agents said they believe Barrett called many hotels to find out where Andrews was staying and requested a hotel room next to hers. Investigators said the eighth video was likely taken at another hotel, which Andrews couldn't identify.
Agents said Barrett, 48, also made reservations at a Milwaukee hotel where she stayed in July 2008. They found her door's peephole similarly rigged, but he didn't check in at that hotel and the furniture in the room did not match furniture seen on the eighth video.
Barrett tried to sell the videos to TMZ, but an employee there informed Andrews' attorneys, according to the complaint.
FBI agents matched information in the e-mail to Barrett, and also examined telephone records and credit card charges from Barrett's Nashville hotel stay. Agents also concluded that the videos of Andrews were likely recorded from a cell phone camera.
Barrett sought to place Andrews under surveillance to harass and intimidate her, and to cause substantial emotional distress, the federal complaint said. He faces up to five years in federal prison if convicted.
A message left at a phone listing for a Michael D. Barrett in Westmont, Ill., wasn't immediately returned Friday night.
Andrews has covered hockey, college football, college basketball and Major League Baseball for the network since 2004, often as a sideline reporter during games.
A former dance team member at the University of Florida, Andrews was named "sexiest sportscaster" by Playboy magazine in both 2008 and 2009. She has been referred to as "Erin Pageviews" because of the traffic that video clips and photos of her generate, and Playboy magazine named her "sexiest sportscaster" in both 2008 and 2009.
