A federal investigation is underway with the United States Postal Service in Centre County.

Penn State issued an alert stating the Inspector General with the mail service is investigating missing or tampered mail.

Students say their family sent them cards with money, but they never received them.

WTAJ reached out to USPS-They have no comment.

In its announcement the University said:

“Penn State is still receiving delivery of mail, although some items may not have been delivered to Penn State at all, and some items received have been tampered with prior to mail being delivered to the University. Unfortunately, this issue is affecting residents both on and off campus and may not be limited to the State College area. “
