TUCSON, Ariz. (AP) -- Authorities say two students at Tucson's Sunnyside High School are in custody for allegedly making online threats against their school. Tucson police said Monday that the two boys -- ages 16 and 17 -- were booked into the Pima County Juvenile Correction Center. Police say the two are each facing one count of interference with an educational institution. Officers were called to a home Sunday after a woman said she saw a remark on her child's Twitter account concerning a threat to the school. Detectives located the boys responsible for the posts. Both claim the posts were meant as a joke and they had no intentions of harming anyone at Sunnyside. Police say detectives didn't find any evidence that the teens had any equipment to carry through with their threats.
