Police are investigating nearly $90,000 reported missing from a fraternity at Penn State University, The Associated Press reports.

State College police say someone at the Theta Delta Chi fraternity reported the money missing, and bank records show about $57,000 in suspicious cash withdrawals from a fraternity bank around between August 2011 and December 2012, according to a search warrant. The warrant also alleges that about $30,000 worth of debit card withdrawals also appeared to be unauthorized.

No one has been charged.
