For the second time in a little more than two months, the Midlothian Independent School District was forced to take action after an incident last Thursday at Frank Seale Middle School.

The middle school was placed on a precautionary lockout on Thursday morning at about 10 a.m. because of an incident involving a student. The school sent out an e-mail to parents and posted on Facebook that there were no weapons and no immediate threat to students or staff.

The nature of the incident was not specified, nor was the identity of the student. The extent to which local law enforcement was called upon to handle the situation wasn’t clear.

The lockout was lifted about two hours later and students were served lunch. All after-school activities were canceled for Thursday evening.

A lockout is different from a lockdown, during which students and staff shelter in place. During a lockout, classes continue as normal, but no outside visitors are allowed on campus.

Nearby Midlothian High School was locked down for about five hours on Sept. 6 after two students reported a possible threat to campus administrators. Two juveniles were arrested in October and charged with making a false report, a state jail felony punishable by between 18 and 24 months of incarceration.
