A swarm of bees stung about 40 students on the campus of Palmdale High School after someone apparently threw an apple at their hive, officials said. Thirty-five people who were stung were transported to hospitals for minor injuries. Witnesses said one person was stung about 13 times. Los Angeles County fire officials responded to the school at around 1 p.m. following a report that multiple students were stung by a swarm of bees. Seven ambulances were sent to the scene. Emergency personnel evaluated up to 40 patients, and a classroom was locked down due to the incident while students fled indoors for their safety.
