School district officials in the suburban Dallas town of Plano canceled Tuesday classes after getting two bomb threats.
The bomb threats, both written on walls, were discovered Friday and Monday. Police say they are unrelated.
Police say a Plano East Senior High student suspected of writing
Friday's threat was arrested Monday. Police say the 17-year-old boy
faces a charge of making a terroristic threat. Police and the district's explosives-detecting dogs found nothing after that threat.
They are still investigating Monday's threat.
Lesley Range-Stanton, a school district spokeswoman, says that
neither threat was deemed credible.
She tells The Dallas Morning News, "This was just extra caution
because of two in a row."
Students, who are off the rest of the week for Thanksgiving break, will not need to make up the school day.
