A bomb threat was left on a voicemail line at Lincoln-Sudbury High School, but officials who searched the school Friday found no suspicious packages, Sudbury police said in a press release.
Police were notified of the threat at 11:30 a.m. "Sudbury Police and Fire Personnel responded to the School and worked in conjunction with Lincoln-Sudbury High School Staff to search the building," the press release said.
By about 1 p.m., "after a thorough search it was determined that no suspicious packages were present."
According to an email sent Friday by Superintendent-Principal Scott Carpenter to parents, students were able to stay at the school and finish their day.
"Given the nature of the threat, police, fire, and school officials ensured that the school was safe for students and staff," the email said. "Student safety is our top priority."
Carpenter did not return calls for comment.
Sudbury police are investigating the threat and asks anyone with information to contact detectives at 978-443-1042.
