PITTSBURG, Kan. (AP) — The former director of Pittsburg State's College of Business is facing federal charges of defrauding Nigerian graduate students recruited to attend the school. Federal prosecutors said Wednesday that 61-year-old Michael Muoghalu of Pittsuburg faces one count of wire fraud and one count of money laundering. Muoghalu is accused of taking more than $148,000 in refunds due to the Nigerian students in Pittsburg State's Masters of Business Administration program. The Pittsburg Morning Sun reports that prosecutors allege that beginning in 2006 Muoghalu worked with an unknown accomplice in Nigeria to persuade 15 Nigerian students to give him part of the refunds they received on deposits for tuition and fees. Muoghalu was suspended in June and resigned September 15. It wasn't immediately clear if Muoghalu has an attorney.
