School officials investigate threat against South Houston High School

Pasadena ISD officials say a threat which was allegedly made against South Houston High School is 'not credible.'

District officials say a student sent a message to several friends which made it onto social media. The district says the threat didn't happen at South Houston High School, and that it was a "very non-specific threat."

The principal of the school has recorded a message for parents that will go out upon dismissal of students today.

School administrators say they have spoken to students about the threat, and that they should inform adults of such threats they hear rather than post them on social media.

Additional officers have been added on campus as a precaution.
