SARATOGA SPRINGS, Utah - Police say a 16-year-old Utah boy with a history of making bomb threats called such a warning into his former high school this week.

Saratoga Springs Police Cpl. Matt Schaerhamer says the call came through Skype, using "fairly sophisticated" methods to mask the address.

The Deseret News reports the teen not only threatened to bomb his former high school, but also threatened to shoot anyone who defused to explosives and demanded $10 million ransom.

Saratoga Springs police arrested the 16-year-old Thursday at about 5:00 p.m. They searched his home but found no explosives.

Local and federal investigators tracked down the student in part by using Facebook.

Authorities aren't releasing his name because he is a minor. They say he is a former student at West Lake High School who has taken to Facebook to threaten violence on schools, law enforcement officers and others.

According to The Deseret News, police believe the teen is responsible for several "swatting" incidents throughout the country and he could face serious federal charges.

Neighbors of the 16-year-old described him as "quiet" and a "computer nerd," reports the paper.

The teen is reportedly being held in a juvenile detention facility in Utah County. Police are not seeking any other suspects.
