In a statement released Friday, Subway said the complaint submitted to its website in 2011 expressed "concerns" about Fogle.<br />Fogle last month agreed to plead guilty to child pornography charges and to crossing state lines to pay for sex with minors.<br />"Since 2011, the company has strengthened its processes for reviewing and escalating customer comments, complaints and inquiries," Subway said.<br />Fogle, who lost 245 pounds by eating nothing but Subway for a year, gave the sandwich shop the image of being a purveyor of healthy options.<br />While Fogle didn't single-handedly turn Subway into what it is today, his story certainly helped the chain's image and popularity.
