Children found bullets on a school bus Thursday morning.

The bus was completing its second route of the day when Summerville Elementary School students found two bullets in the back, Dorchester District 2 spokeswoman Pat Raynor said.

The bus dropped off Summerville High School students earlier in the morning, Raynor said.

Summerville police and school officials pulled students who had been on the bus out of class, questioned them and searched their lockers, Capt. Jon Rogers said. No further ammunition or weapons were found, he said.

The high school was not placed on lockdown during the search, Raynor said.

The principal of the elementary school questioned the students who were on the bus later in the day, and one of them admitted having bullets on the bus, Raynor said.

The student will be recommended for disciplinary action, she said.

Parents were notified of the incident as a precaution, she said.
