UPDATE: 9:30 p.m. EDT — Utah county officials formally identified Monday the suspect who issued a bomb threat against an elementary school as 35-year-old Christopher Craig. A resident of Eagle Mountain, Craig was taken into police custody after a standoff with several law enforcement agencies at Eagle Valley Elementary School.

Craig was taken to the Utah County Jail and was booked under several charges, including terrorism and disrupting the operation of a school.

UPDATED: 7:18 p.m. EDT — The person who reportedly issued a bomb threat against an elementary school in Utah is in police custody, according to a report on social media. The suspect, though not confirmed, was identified as possibly being Chris Craig, a former college basketball player and coach who has in the past referred to himself an "Islamic jihadist."

The El Paso Times received an email hours before the alleged bomb threat prompted local law enforcement to respond to the Eagle Valley Elementary School in Eagle Mountain. The email, sent from an account with the name Christopher Craig, said in part that he "will call 911 with a threat of an explosive and drive onto my 9yr olds elementary school, Eagle Valley Elementary, with a True Explosive." The email went on to say he was "born into this world under the slave name of Christopher Craig.  Currently, I am known as The Radical Islamic Jihadist Muhammad Allah Al-Khidr."

Law enforcement has not officially identified the suspect in custody.

Original story:

All of the students at an elementary school in Utah have been evacuated following an apparent bomb threat. An unidentified man walked on the Eagle Valley Elementary School campus, went inside and told officials there no one would be hurt if everyone evacuated immediately, local news outlet KUTV reported.

The man inside the school could be a former college basketball player, who authorities say sent a note to Utah media earlier in the day advising that he "will call 911 with a threat of an explosive and drive onto my 9yr olds elementary school, Eagle Valley Elementary, with a True Explosive," the El Paso Times reported. Chris Craig played college hoops at the University of Texas-El Paso.

The email purportedly from Craig suggested there may be an element of terrorism at play, saying in part that he "was born into this world under the slave name of Christopher Craig. Currently, I am known as The Radical Islamic Jihadist Muhammad Allah Al-Khidr."

The email went on: "My reason for writing Today is because of my pending arrest and hunger strike which begins when I press send on this Discourse of Truth.  In 2 hours, call Eagle Mountain PD in Eagle Mountain, UT if you think I am bluffing.  Ask them."

Law enforcement set up a perimeter around school grounds in the town of Eagle Mountain and emergency crews responded in part with military-styled armored vehicles after reports from local journalists surfaced on social media of a man wearing a mask being inside the school. 

A Facebook Live video posted by a user named Kyla Moulton showed one apparent member of law enforcement with his weapon drawn and aimed at what appeared to be the school's front.

Craig is also the former head basketball coach at Utah State University Eastern and has a history of being arrested during incidents in which he has called himself an "Islamic jihadist," the Salt Lake Tribune reported.

He was previously arrested for driving his car onto a school playground in the state's Carbon County, according to a tweet from a local journalist.
