BOCA RATON, Fla. — Boca Raton police have given the all clear on Monday afternoon after investigating a report of a possible armed person at Boca Raton Community High School.

In a post on X just before 12:30 p.m., the Boca Raton Police Department said officers responded to the school, along with members of the School District of Palm Beach County's Police Department, "in reference to a report of a possible armed subject on campus."

Roughly 90 minutes later, at 2 p.m., the police department said that after sweeping the campus, "At this time, all is clear," adding that nothing suspicious has been found.

In a callout to parents and guardians, the School District of Palm Beach County said Boca Raton High School "has been given the all-clear by police. All students and staff are safe."

"Details regarding dismissal will be provided via email, phone call, and posted to our website. Please do not come to campus at this time," the district said in its message.

In an earlier callout to parents and guardians, the district said "there is no verified threat to the campus."

Parents were told to head to the parking lot of the Cinemark on Airport Road. Once in the parking lot, parents got updates from the school's assistant principal. But most parents were seen on their phones trying to stay in contact with their kids.

"It's the unknown, it's the unknown of what it is, of what's going on," Evan Gallahoun told WPTV's Todd Wilson.

He and hundreds of other parents were frantic to know if their kids were safe or in harm's way.

"Getting pictures and videos of my kid in the closet is a little frightening," Dana Abraham said.

What happened at Boca High isn't a one off. A similar situation happened Monday at Hialeah Senior High School in the Miami-Dade County Public Schools.

"This is a sight that we're seeing too many times in our country right now, which is just horrible," Lev Parnas said.

The report of the possible armed person came through SaferWatch, a mobile panic alert app, according to the Boca Raton Police Department.

According to Boca Raton police, the school district is now investigating where the anonymous threat came from.
