HOUSTON – At least 14 Houston Independent School District schools received envelopes Friday containing a white powdery substance, according to an HISD spokesperson.
A Houston Fire Department hazmat team was sent to each school to collect the envelopes.
Preliminary testing showed the substance appeared to be non-hazardous. The powder was tested for radiation, explosives and volatile chemicals and further tests are being conducted.
The schools were Alcott Elementary, Almeda Elementary, Anderson Elementary, Ashford Elementary, Attucks Middle School, Barrick Elementary, Bastian Elementary, Black Middle School, Blackshear Elementary and Browning Elementary.
Fonville Middle School, Briar Meadow Elementary School, Bellaire High School and Burbank Middle School were added to the list Friday evening.
HISD said its top priority is making sure all schools are safe before stud
