One day after a shooting threat hoax caused a lockdown, New Prague middle school students were evacuated once again after officials received a bomb threat.

The threat -- which came from a call directly to the New Prague police department -- claimed that a bomb would go off at 9:01am, though no explosion occurred.

The New Prague superintendent also received a threatening email at 8:30am this morning, with the subject line: "Read or die."

Students were cleared to return to class shortly before 10:00am.
