A college professor who helped the FBI investigate mortgage fraud cases was indicted Thursday for running a similar scam, the Cleveland Plain Dealer reports.

Paul Tomko, an adjunct professor Cuyahoga Community College in Ohio, faces eight counts of fraud and conspiracy and making false statements to his probation officer.

Tomko, 39, told the Plain Dealer he is innocent.

“I have no idea what they’re talking about,” he said. “We certainly plan to fight this.”

In 2007 and 2008, the FBI paid Tomko $27,000 to help agents in mortgage fraud investigations.
