MARBLEHEAD — Police detectives say they have unraveled the mystery of who used an electronic social media app called Yik Yak to make a bomb threat at the high school on March 4.
The juvenile, whom police did not identify, will face charges in Lynn Juvenile Court of making a bomb threat and disrupting a school assembly, according to a message posted on the department’s Facebook page.
“Since that time, Marblehead police detectives, with the cooperation of school officials and the developers of the ‘app,’ have been investigating this incident,” the message says. Detectives were able to identify a suspect.
The suspect, a Marblehead High student, was interviewed and confessed, police said.
A second threat received that day is still under investigation.
The threats caused quite a commotion at the school. The first threat that Tuesday came in at 10:55 a.m., and it led to the school’s evacuation. The school was not declared safe until 12:15 p.m. The second threat came in at 1:30 p.m., and the school was evacuated again.
School officials that day had appealed to students not to use the messaging platform out of concern that it was being used to bully others. Yik Yak allows one to post messages anonymously.
