(Reuters) - Police in Utah have arrested two high school students accused of making detailed plans to bomb a school assembly and then escape in a plane they planned to fly themselves, police said on Thursday.
The duo, 18-year-old Dallin Morgan and 16-year-old Joshua Hoggan, were arrested on Wednesday after being pulled out of classes at their high school in the city of Roy, about 30 miles north of Salt Lake City, Roy Police spokeswoman Anna Bond said.
"Initial investigative discovery has uncovered a plan to use explosives during a high school assembly," Bond said in a statement.
"Maps of the school and information about security systems had been prepared with plans for an escape using a plane from the Ogden Hinckley Airport," she added. "Self-taught usage of technical flight simulation programs were used in the planning and preparation."
