An FBI spokesperson declined to confirm to Fortune that a raid happened at Fogle’s home, but did say “the FBI is conducting investigative activity in the area, the nature of which cannot be disclosed at this time.” A photograph apparently showing Fogle being escorted into his house by law enforcement was circulating on Twitter Thursday morning.

Fogle has represented Subway for more than a decade, beginning after he lost 245 pounds after eating only Subway sandwiches—one six-inch turkey sub and one twelve-inch veggie sub each day—for a year, in addition to an exercise routine. He became the face of the sandwich chain’s healthy eating-focused advertising campaign, gaining national fame for his Subway promotional pictures that featured his smiling face and former 60-inch waist pants.

In April, the executive director of Fogle’s Jared Foundation, founded to combat childhood obesity, was arrested on child pornography charges.

In a statement issued Tuesday afternoon, a Subway representative said the company “shocked by the news and believe[s] it is related to a prior investigation of a former Jared Foundation employee.” Fogle’s lawyer, Ron Elberger, also released a statement Tuesday afternoon, saying that his client “has been cooperating, and continues to cooperate with law enforcement in their investigation of unspecified charges.”
