Subway spokesperson Jared Fogle's home has been raided in a child porn investigation, according to multiple reports.

FBI sources told FOX59 that federal and state authorities were raiding his house in Zionsville, Indiana, on Tuesday morning. Search warrants were reportedly issued in an ongoing case involving Russell Taylor, the former director of the Jared Foundation, who was arrested for child pornography in May.

WTHR reports the Indiana Internet Crimes Against Children task force is removing electronics from Fogle's home for analysis in a forensics van in his driveway. Fogle has been detained outside the house, but is not under arrest.

Fogle, known to millions as "the Subway guy," started the Jared Foundation in 2004 with the sandwich chain to raise awareness about eating healthy with a goal of eliminating childhood obesity. He spoke in Syracuse in 2011 at the American Heart Association's Heart Walk about his own battle with obesity, losing 244 pounds in one year by walking at least 30 minutes each day and eating two low-calorie Subway subs daily.

According to FOX59, the 37-year-old Fogle said the foundation severed all ties with Taylor following the arrest.

The Indianapolis Star reports Taylor, 43, faces seven counts of production of child pornography and one count of possession of child pornography. State police detectives began investigating him after a woman reported receiving texts of a sexual nature from Taylor when he asked about pictures of young girls.

A search at Taylor's home found more than 400 videos of child pornography, the Star adds. Court documents have identified four minors as victims in the case.
