ECTOR, Tex. -- Three juveniles are in custody after police say they threatened Ector school students and staff. Officials cancelled classes on Thursday as a precaution, and are informing everyone of the threat on Friday.

Candice Ostrowski was shocked when she heard the news that three of her fellow students threatened to harm her teachers and friends.

Officials were just as surprised to hear about a threat of this magnitude in their community.

School officials received a call Wednesday afternoon of what they are calling "a terroristic threat" on the school. After a preliminary investigation, Ector and Fannin County authorities found evidence on a student’s MySpace page confirming the rumors.

That’s when authorities say they acted quickly.

Because they couldn't arrest the individuals Wednesday night, Ector ISD officials cancelled school Thursday, telling students and family it was due to a gas leak.

"I had to come up with something that was serious enough that you will close school down," Gary Bohannon, Ector ISD superintendent, said.

Ector Police arrested three juveniles Thursday in connection with the threat. They are being held in a juvenile detention center. A hearing on Monday will determine what charges will be filed against the three.

Parents were updated on the situation on Friday and agree the right steps were taken, even if the threat never would have materialized.
