According to APD, Montes called the Amarillo Emergency Communications Center around 7:30 a.m. and threatened to blow up one of the locations. School administrators were made aware of the call and evacuated children from the building safely.
Police said Montes then made a second phone call and threatened to begin shooting at students at the other Head Start location on Nelson Street.
Montes was identified as a suspect shortly after and was arrested in a residence in the 1500 block of North Cleveland Street.
Montes' charges are a third degree state felony, according to police. It carries a sentence of up to ten years in prison and a $10,000 fine.
Head Start is a community-based prekindergarten program operated by Region 16.
