Nosing around

A bomb-sniffing dog sweeps Newport Beach's Horace Ensign Intermediate School after a student alerted campus security to what he thought were drugs in another students possession. After searching the 12-year-old's locker, police found bomb-making materials and immediately locked down the school. No one was harmed and the boy was arrested and booked on suspicion of felony possession of an explosive device. Mark Boster / Los Angeles Times
