Hoax Bomb and Gun Threat Prompts Brief Lockdown at Frisco Memorial High

A campus resource officer at Memorial High School in Frisco initiated emergency procedures after an unknown caller told the officer they were outside the campus with a firearm and that a bomb had been placed on school grounds, prompting a lunchtime lockdown. The call triggered an immediate law enforcement response and multiple agencies converged on the campus.

According to district and police accounts, the initial lockdown began around 12:30 p.m. The campus status shifted in some accounts about 30 minutes later to a “hold” in which students remained in classrooms, and Frisco ISD and local media reported the all-clear and resumption of normal operations at roughly 2 p.m. The incident date reported by officials was March 5, 2026.

Frisco Police Department officers, assisted by bomb-detection K-9 teams, conducted sweeps of classrooms and the parking lot and did not locate any hazardous device or weapon. Police labeled the call a hoax and said there was no danger to the public. A social-media post from a student on a community forum described “dozens of cops and some k9 units around the perimeter” while administrators told students there was “no immediate threat anymore” and that teachers and parents would be notified.

Frisco ISD issued a statement praising school response and student behavior, saying, "Students and staff did an excellent job following safety protocols throughout the situation. Because the incident occurred during lunchtime, the campus also ensured that students who missed their lunch period had the opportunity to receive a meal as normal operations resumed." The district added, "Frisco ISD appreciates the swift response and partnership of the Frisco Police Department in helping ensure the safety of students and staff."

As of the latest reports, Frisco Police have not said whether any suspect has been identified in connection with the hoax call. Media accounts and the district stressed the SRO’s quick action in initiating procedures; officials did not provide a timeline for any investigative steps such as phone tracing or charging decisions.

The March 5 scare comes after other threat-related disruptions in the district earlier this year, including emailed threats in January that briefly put all district campuses into a modified secure status. Law enforcement and legal analysts have used the term "swatting" for hoax calls that prompt armed responses, and federal and state prosecutions have followed similar incidents elsewhere, according to national criminal-justice analyses. Memorial High students returned to class and were provided meals after the lockdown was lifted and campus operations resumed.
