Fogle's neighbors said they were shocked by what was unfolding at the house and he usually kept to himself.
Fogle’s organization -- The Jared Foundation -- made news in April when the executive director was arrested on charges of child pornography.
Russell C. Taylor, 43, was charged with seven counts of production and one count of possession of child pornography in early May.
IMPD found evidence of pornography while executing a search warrant.
A spokesman for Fogle released a statement following Taylor’s arrest:
I was shocked to learn of the disturbing allegations against Mr. Taylor. Effective immediately, the Jared Foundation is severing all ties with Mr. Taylor.
Taylor held the position with Fogle’s foundation for seven years.
A statement from Subway indicates the company thinks Tuesday's investigation was related to Taylor's case.
"We are shocked about the news and believe it is related to a prior investigation of a former Jared Foundation employee. We are very concerned and will be monitoring the situation closely. We don't have any more details at this point."
Subway announced later Tuesday afternoon that it is suspending its relationship with Fogle amid the investigation.
"Subway & Jared Fogle have agreed to suspend their relationship due to the current investigation. Jared is cooperating with authorities," the restaurant wrote on its Twitter page.
