Police are investigating a bomb threat called into the front office at Catonsville High School after 2 p.m. Monday, right before the school's normal dismissal time at 2:15 p.m., according to Baltimore County Police spokesman Cpl. John Wachter.
Students were evacuated from the school by police after receiving notification of the threat at 2:08 p.m. from a school resource officer on the school's campus, Wachter said.
Police searched the areas around and inside the school and did not find anything suspicious, said school principal Bill Heiser in an audio message sent to students and parents.
"Police determined our school to be clear and safe at 3:30 p.m.," Heiser said. "We want to commend our front office staff, students and teachers as well as our county police and fire department colleagues."
The school system is working with police to find out who was responsible, said Mychael Dickerson, a Baltimore County Public Schools spokesman.
"There is no reason to believe that the school is not safe," Dickerson said.
There is no suspect information available and no injuries were reported, Wachter said.
