Man Held in Alleged Threats to LA Schools Police have arrested a man for allegedly posting Facebook threats against Los Angeles elementary schools. Officer Venus Hall says weapons were confiscated when the man was arrested at his home Sunday afternoon by officers in the Northeast Division, an area covering east Hollywood to Glassell Park and Silverlake. He remains in the downtown jail. The location of the arrest and information about the man and the nature of the threats are being withheld. Details on the weapons also haven't been revealed. Students in the Los Angeles Unified School District are on winter break. Cmdr. Andrew Smith says police are taking threats very seriously. The arrest came two days after 20-year-old Adam Lanza shot and killed 20 children and six adults before killing himself at Sandy Hook Elementary in Newtown, Conn.
