South Wales Police say information that led to the closure of two Cardiff schools this week is now being investigated as 'malicious communications'.

The investigation follows threats made via live chat at around 8.30pm on Sunday night, targeting Llanishen High School and Eastern High School.

Police have confirmed additional communication was received last night, concerning St Illtyd’s High School.

Extensive enquiries have been conducted, including thorough searches at all schools.

Police have found no evidence of anyone posing a threat at these locations.

Superintendent Matthew Codd of South Wales Police said: "We understand that events this week have caused concern and disruption for parents and the community.

"While the investigation continues to determine the origin of the malicious communications, we would ask people to avoid spreading rumour and misinformation, and to only share information from official sources.

"We thank the schools, parents and the wider community for their support and understanding."
