PORT ARHUR, TX -- Students and faculty at Memorial High School were told to shelter in place for a brief period of time after a threat was made to the school. Four suspects were apprehended. Of those four suspects, three were students at Memorial and one suspect was not a student.

Just before 9:30 Wednesday morning, Dr. Glenn Mitchell, principal at Memorial High School tells 12News, a receptionist received 5 phone calls from the suspects asking to speak with a male administrator with whom they had a problem and the 5th call, the caller used foul language and threatened the school. That's when administrators called for a shelter in place.

Dr. n Mitchell says students and staff safety is always top priority.

"From that procedure all students were comfortable and hallways were clear. Parents were called and notified by the 'shout out system' that we have and use if there in an incident of trouble, and that the trouble had been subsided and resolved."

The school used a "Stay Home Drill," which is protocol used to keep students and staff to stay in place until administration knows the nature of the situation. School officials say the administrator who the suspects were angry with is okay and finished out his work day.
