HOUSTON - The Spring Branch Independent School District said early Tuesday officials were investigating a threat posted on Facebook that referenced Memorial High School.

A statement released by SBISD said parents were notified of the threat by phone and e-mail. Apparently the message was posted on a non-school related Facebook page called MHS Confessions.

SBISD police and district tech support were working to track down the source of the message.

The district said additional police would be present on campus all day Tuesday.

Anyone with information or concerns can call SBISD Police at 713-984-9805.
