Police were requested to assist with an investigation at Arroyo Grande High School Friday.
Police are releasing limited information about the alleged "school safety incident," only saying it appears to have been a rumor that started on campus and officers responded to assist the school resource officer and school officials with the investigation at the request of school administrators.
"As a result of the investigation it was determined there was no concern for the safety of the school, or any of its students, in relation to this reported incident," police said in a press release.
Classes continued as normal during the investigation.
Police say following the investigation, a fire alarm sounded due to smoke from over-cooked food.
The incidents were not related but did cause concern among students.
Police were unsure when the school notified parents.
KSBY has reached out to the Lucia Mar Unified School District for comment but has not yet heard back.
