An 18-year-old high school student from the greater Boston area has been arrested and charged with making terroristic threats after police were alerted to "disturbing verbiage" on his personal Facebook page. Authorities have set bond at one million dollars for Cameron B. D'Ambrosio of Methuen, MA following a Thursday afternoon arraignment one day after he was apprehended at his home around 30 miles north of Boston. Police say D'Ambrosio, a senior at Methuen High School, authored eye-catching messages this week with his personal social networking account.
