A 16-year-old Key West High School student was found with a handgun on campus Friday, according to the Monroe County School District.
The boy was arrested on a charge of possession of a concealed weapon and taken into custody.
Another student reported seeing the student in a restroom with the gun, which according to the police report was a black Walther PK380.
The teen admitted to police he had it in his bookbag and was planning on selling it to another student for $500.
“Administrators are working with law enforcement in handling the investigation,” said schools spokeswoman Lynsey Sanders.
“All students are safe,” said Sanders, on Friday afternoon.
The 16-year-old, who was not identified, told investigators he found the gun inside a car on Summerland Key late Thursday night.
It’s the second criminal incident to happen at a Monroe public school this week.
On Wednesday, a 14-year-old boy was taken into police custody after two other students at Key Largo School took Xanax and were sent to the hospital.
The boy who police say gave the other students the drugs is being held by the Department of Juvenile Justice on felony drug distribution. Police found a bag with 20 to 25 Xanax pills at the school, he said.
