Birmingham Residents Detained in Connection with Cardiff School Threats
Three individuals from Birmingham have been taken into custody following a series of alleged threats that disrupted education at multiple Cardiff secondary schools earlier this month. The arrests come after what authorities describe as "anonymous online threats" that created significant concern within the community.
School Closures and Police Response
Between March 15 and 18, 2026, a disturbing series of threats targeted three educational institutions across Cardiff. The situation escalated to the point where Llanishen High School and Eastern High School were compelled to close their doors for two full days as a precautionary measure. Police officers, including armed units, were deployed to both locations to ensure safety and conduct investigations.
South Wales Police confirmed on Tuesday that they have arrested two adults—a 44-year-old woman and a 47-year-old man—along with a 12-year-old child, all residents of Birmingham. The trio faces suspicion of committing a bomb hoax under the Criminal Law Act 1977 and currently remain in police custody while inquiries continue.
Nature of the Threats and Community Impact
The alleged threats initially surfaced through the police's online chat function on Sunday, March 15, targeting Llanishen High School and Eastern High School. The threats were subsequently extended to include St Illtyd's High School, though that institution did not close. According to information shared with local councillors, the communications referenced "explosive devices, firearms and knife attacks", prompting immediate concern among authorities.
Following extensive discussions between South Wales Police and Cardiff Council officials, a joint decision was made to temporarily close both affected schools. This precautionary action was taken despite no evidence suggesting any individuals had attended the schools with malicious intent.
Official Statements and Ongoing Investigation
Assistant Chief Constable Thomas Williams addressed the community's anxiety, stating: "We understand the considerable concern this incident has caused parents and the community. We take these reports extremely seriously and investigations are ongoing." He further reassured families that "there remains no evidence of any persons attending any of the schools involved posing a threat."
A South Wales Police spokesperson elaborated on the arrests, noting they were made specifically in connection with threats directed toward Cardiff secondary schools during the March 15-18 timeframe. The police force emphasized their continued collaboration with educational partners and expressed gratitude for the support shown by schools, parents, and the wider community during this unsettling period.
The investigation remains active as authorities work to determine the full circumstances surrounding the alleged hoax threats and the involvement of the Birmingham residents now in custody.
