HISD seeks ‘vigilance’ Thursday after threat to schools

All Houston ISD campuses are opening Thursday morning despite a threat of violence – but with a request for parents and students for extra vigilance about “any suspicious activity.”

HISD put out a robo call to families and staff late Wednesday night after a threat, similar to those received by Los Angeles, New York and Miami schools this week, was delivered to the district here.

“At this time, we do not believe the threat is credible, but as a precautionary measure law enforcement officers are in the process of conducting random sweeps of school district buildings to ensure student safety,” HISD said in a statement. “Surrounding law enforcement agencies also have been notified and additional officers will be on patrol Thursday morning.”
