Houston police and the FBI are investigating a suspicious package found at an HISD elementary school.
Around 9:30 a.m. Wednesday, police were called to Crockett Elementary School after a secretary discovered a powdery substance inside an envelope she opened.
As a precaution, the office area was isolated and the air conditioning turned off. Students were not evacuated, but they were kept in their classes during the investigation. The scene was cleared by 11:00 a.m.
The FBI and other authorities continue to investigate this matter.
