About 30 Quince Orchard High School students were stung by a swarm of bees on their way to school Thursday morning, said a Montgomery County schools official.
Spokesman Derek Turner said a swarm of bees was riled up across the street from the high school, on a path many students take during their walks to school.
Montgomery County Fire & Rescue personnel responded around 8 a.m. to monitor students and provide any treatment necessary in the case of an allergic reaction, Turner said.
Pete Piringer, spokesman for Montgomery County Fire & Rescue, wrote on Twitter that three patients were transported to a hospital and others were evaluated at the scene. All injuries were not life threatening, Piringer wrote.
Units are searching for the source of the swarm, Piringer said, and it is believed the bee hive is off-campus.
