A 13-year-old boy was arrested Friday in connection to a threat, causing the school to go on lockdown.
The teen was booked into the Pima County Juvenile Detention Center on suspicion of a hoax and interference or disruption of an educational institution, said Deputy Ryan Inglett, a Sheriff's Department spokesman.
Both charges are felonies.
Gerad Ball, principal of Coronado K-8 School, said that the lockdown was lifted by 11 a.m. in a post on the school's home page. He said during the investigation it was found that students and staff were not in danger at any time.
Authorities, who were notified by administrators about the threat about 10 a.m., determined that the boy in Friday's case also was responsible for a similar threat Aug. 25 at the school, Inglett said. He said that threat did not warrant a lockdown.
Both threats were written to solicit a response from school administrators and law enforcement, said Inglett. The threat on Friday was written on a bathroom wall, and was aimed at the school.
No further information about the threats were released.
