A former franchisee alerted a Subway advertising executive in 2008 about her concerns about pitchman Jared Fogle, according to her lawyer.
Cindy Mills exchanged phone numbers with Fogle after they met at an event, said Robert Beasley, a lawyer who represents Mills.
After Fogle began talking about paying for sex with minors, Beasley said Mills alerted a regional Subway contact in Florida where she is based. Later, she alerted Jeff Moody, who was in charge of the Subway Franchisee Advertising Fund Trust, he said.
Subway did not respond to a request for comment Thursday.
The company has previously said it does not have a record of Mills' complaints, which were previously reported by Business Insider. The publication initially kept Mills' identity anonymous at her request, but identified her Thursday.
