A Web site that let anyone with an Internet connection and a printer create fake airline boarding passes has been shut down after federal agents visited the creator.

FBI agents raided Christopher Soghoian's home over the weekend, seizing computers and other equipment, Soghoian wrote on his blog. They first visited him Friday afternoon with a request to take the site down, but when he got online, he found that the site had already been removed, he wrote.

Soghoian, reached via e-mail on Monday, declined to comment for this story, citing advice from his lawyers to lie low.

Wendy Osborne, a spokeswoman for the FBI's Indianapolis office, confirmed that agents had searched Soghoian's home as part of a joint investigation with the Transportation Security Administration. "We will conduct a thorough and complete investigation," Osborne said. "We are certainly concerned with any potential breach in security, particularly at the airports.
