Palm Beach police told the Post that the teens, all 15-year-old boys, were arrested not long after they entered the grounds of the property, which is currently closed, and after they disposed of the backpack, which contained a Mini Draco 7.62 caliber AK-47 with a loaded magazine.

"They had no idea where they were," department spokesperson Michael Ogrodnick said, noting that they were lucky that the Secret Service wasn't there.

"Honestly, I really don't believe they even realized where they were in terms of location and proximity to Mar-a-Lago," he added.

The police report states that the teens were seen sitting in a parked car near the resort at around midnight on Thursday, and sped off without headlights on after officers approached. They stopped the car near Mar-a-Lago and ran after a second police vehicle tried to cut them off near South Ocean Boulevard. Police alerted resort security, who located the teens' backpack on the property.
