PLANO, Texas - Plano police investigated threats reported at four different schools on Monday.
A student who recently transferred out of state was allegedly behind a social media threat that mentioned a shooting at Clark High School.
Investigators said in a separate incident, a student at Hendrick Middle School altered that social media post to indicate a shooting would happen there.
Both of those students were identified and could face criminal charges.
Clark High School will have extra security this week as a precaution.
