SAN MARCOS, Texas -

An emergency alert was canceled at Texas State University early Thursday afternoon following a bomb threat.

According to university spokesman spokesman Mark Hendricks, the all clear was issued a little after 12 p.m. after the Texas State University Police Department and the Austin Police Department Bomb Squad determined there was no bomb.

Hendricks said the threat was delivered via email at 7:21 a.m. to a Houston-area admissions counselor who works out of her home. When the counselor discovered the bomb threat, she alerted her supervisors, who in turn alerted university police.

The Tower and San Jacinto residence halls, which were closed during the emergency, have been reopened. As a precaution, the Admissions Building will remain closed Thursday.

All classes will be held according to normal schedule, Hendricks said.
