Overview
- Llanishen High and Eastern High shut for two days after a live‑chat threat on Sunday night, with a later message referencing St Illtyd’s High.
- Extensive searches and intelligence reviews found no evidence of anyone attending the schools to cause harm.
- A multi‑agency assessment judged the communications disruptive rather than credible, and the police critical incident was stood down.
- Investigators say the sender remains unidentified and used anonymised VPN routing, with inquiries continuing.
- Cardiff Council says both affected schools will reopen on Wednesday with reassurance measures following meetings with staff.
