Prosecutors say nine current and former employees at Northern Illinois University are facing charges in an alleged scheme to sell the school's scrap materials and put the cash in a private bank account.

The DeKalb County State's Attorney's Office on Tuesday announced the filing of charges in the case, including felony theft, felony misconduct and obstruction of justice.

Prosecutors say employees working at a campus physical plant allegedly sold scrap metal, including some from campus building renovations. Authorities say the money was put into an account dubbed the "coffee fund" and the cash was used for social events, including retirement parties.

Records dating to 2005 show the fund had paid over $13,000.
