A vague threat circulating on TikTok and other social media sites about a “National School Shooting Day” has prompted concern among parents across the country, but the Long Beach Unified School District said Thursday evening that local schools will be open Friday. Local and state law enforcement don’t believe the threat is credible, LBUSD officials said.

In an email to parents of the 70,000 students in the LBUSD, officials said they were aware of the “anonymous general threat communicated through TikTok and social media against schools nationwide.” The posts referred to Friday, Dec. 17 as “National School Shooting Day.”

According to the LBUSD’s message to families, “State and local law enforcement officers have investigated the threat, did not find any specific links to Long Beach Unified School District, and have determined the threat is not credible.”

LBUSD schools will open as scheduled for Friday, the final day before the district’s two-week winter break. Friday is a shortened minimum day schedule at all schools.

“Local law enforcement continues to work with our district to support the safety of our students and staff,” reads the email, which is signed as being from Long Beach Unified School District administration. “As always, we urge anyone with information that could impact the safety of our school community to immediately call 911 and make a report.”
