OMAHA, Neb. (AP) — An Omaha man hired to monitor programs that receive money from Omaha billionaire Warren Buffett’s charitable foundation has pleaded guilty to stealing from the organization.

Dhaval Patel pleaded guilty Tuesday to stealing $46,000 from the Buffett Foundation. The 38-year-old Patel is set to be sentenced in November, when he faces up to 20 years in prison.

Police say another foundation employee checked with a London hotel from which Patel had submitted a receipt for reimbursement and learned that Patel hadn’t stayed there. A check of other expense receipts turned up what police believe was tens of thousands of dollars in fraudulent receipts.

The newspaper says Patel, who was paid $190,000 a year as a senior program officer, has repaid $46,000 to the charity.
