Authorities say a former police officer threatened to expose alleged criminal activity at a Philadelphia-area junior college unless the school waived his son's housing bill.
Prosecutors charged 55-year-old Vincent Gaudini of Philadelphia with extortion and other offenses for allegedly sending a threatening e-mail to Harcum College in Bryn Mawr.
The message said Mr. Gaudini would tell authorities about alleged drugs and guns on campus unless it dropped a $3,000 dorm fee.
Montgomery County authorities say they found no truth in Mr. Gaudini's allegations.
Mr. Gaudini was arraigned Wednesday and released on bail; he could not be reached for comment Friday. He left the Philadelphia police force in 1985 on a disability.
A spokesman for Harcum declined comment.
