Weapons Found in Cardiff School Searches, Safety Concerns Rise 2026

Key Points

• Nearly two‑thirds of weapons‑related searches at schools in Cardiff found pupils carrying weapons between September 2025 and March 2026.
• A Freedom of Information (FoI) request obtained by BBC‑produced Newyddion S4C showed that 12 out of 19 searches in Cardiff schools uncovered weapons on pupils.
• The NASUWT teachers’ union has described the figures as “frightening” and said that even one weapon‑carrying incident would be one too many.
• Cardiff Council has stated that protecting staff and pupils on educational sites is a priority and has introduced new guidance and hand‑held scanners for searches in all schools.
• Medical student and StreetDoctors volunteer Millie‑Mae Adams said that young people carrying weapons is an “emergency” and “a big problem”, and that many wrongly believe they are protecting themselves.

How widespread is the issue in Cardiff schools?

Cardiff – Cardiff Council schools and governing bodies have recorded that weapons were found in 12 out of 19 searches carried out between September 2025 and March 2026, according to results of a Freedom of Information request shared with BBC‑produced Newyddion S4C. That means more than 60 per cent of searches carried out in that six‑month window led to weapons being discovered on pupils, while no weapon was found in the remaining seven searches.

NASUWT, the teachers’ union, has warned that the pattern is “frightening” and that the rising number of weapon‑related incidents is of major concern. Sion Amlyn, policy and case officer for NASUWT in Wales, said:

“If one weapon was found, it would be one too many, so the fact that this appears to be increasing is frightening… and the fact that there are multiple cases is concerning.”

What new measures has Cardiff introduced in schools?

Cardiff Council introduced fresh guidance on weapons in schools and educational sites in September 2025, at the same time as rolling out hand‑held scanners to every school in the county. The guidance states that staff may conduct a search if there is “reasonable suspicion” that a pupil is carrying a knife or other weapon, and this can be based on reports from staff, pupils or parents, or on observed behaviour or CCTV.

The council emphasised that searches are carried out discreetly, proportionately and with clear explanations to the pupil, and that parents or carers are informed afterwards. A spokesperson for Cardiff Council said:

“If there is reasonable suspicion that a young person may be carrying a weapon, schools have the legal power to carry out a search, which is done discreetly, proportionately and with clear explanations provided to the young person and parents or carers are informed following any search.”

Cardiff’s approach follows earlier powers granted to Welsh schools by the Welsh government in 2013, which enabled schools to screen pupils for knives or other weapons and to search those suspected of carrying them. However, union officials have pointed out that while Cardiff has introduced consistent local guidance, there is still a lack of uniformity in how searches and follow‑up procedures are applied across all schools in Wales.

What do experts and advocates say about pupils carrying weapons?

Millie‑Mae Adams, a medical student volunteering with StreetDoctors in Cardiff, told Newyddion S4C that the scale of weapon‑carrying among young people is an “emergency” and “a big problem”. Adams, who grew up in Caerau, Cardiff, said that the reported numbers may surprise the general public but are not surprising to those who speak directly with young people.

She explained:

“Young people have this idea that they’re protecting themselves by carrying it [a weapon] but that isn’t true.”

Adams, who became interested in medicine partly because of witnessing violence and the threat of violence in her community, hopes that StreetDoctors’ work can help steer young people away from carrying weapons. She added that the issue is likely even more widespread if all schools in Wales were included, saying:

“I think that number would be much higher if you looked at all schools in Wales – on the streets people are carrying weapons and knives.”

What national and local context surrounds search powers in Welsh schools?

Wales has allowed schools to screen pupils for knives and other weapons since 2013, under Welsh government legislation. Cardiff’s new guidance, introduced in September 2025, builds on that framework by setting out detailed procedures for when searches may be carried out, how staff should use hand‑held wands to minimise physical contact, and what steps follow any discovery.

Cardiff Council’s education cabinet member has acknowledged that parents may feel uneasy about the idea of pupils being searched, but stressed that such actions are not routine and should not be conducted lightly. The council has also pointed out that the six‑month FoI data cover only a limited number of searches, and that the aim of the new measures is to deter weapon‑carrying rather than simply to record incidents.

Meanwhile, the NASUWT has backed the principle of using statutory search powers where necessary, but has highlighted concerns about inconsistency in how schools interpret “reasonable suspicion” and how they apply consequences. The union has called for clearer, Welsh‑wide protocols on when searches are justified, how staff should be trained, and what discipline and support measures follow when weapons are found.

Background of the particular development

Cardiff’s rollout of weapons‑search guidance and scanners follows a broader debate in Wales about how schools should respond to rising concerns about youth violence and knife‑carrying. In recent years, police and local authorities have reported spikes in incidents involving young people with knives and other weapons, prompting calls for stronger preventative measures in schools and communities.

The Cardiff scheme, introduced in September 2025, is among the most systematic local efforts so far, standardising search procedures and equipping every school with hand‑held scanners. At the same time, national bodies and charities such as StreetDoctors have pushed for more education and outreach programmes to address the underlying reasons why young people feel they need to carry weapons.

However, some education and legal experts have warned that while scanners and searches can act as a deterrent, they must be balanced against students’ rights, privacy, and trust in school staff. Cardiff’s guidance attempts this balance by limiting searches to situations where there is reasonable suspicion and requiring clear communication and follow‑up with parents.

Prediction: How this development could affect Cardiff’s pupils and communities

If the current pattern of weapons‑related searches continues, Cardiff schools may face greater pressure to expand or refine their scanning and search protocols, while also investing more in pastoral support and violence‑prevention programmes. Teachers and union representatives could respond by demanding clearer, Wales‑wide rules on search powers and discipline, arguing that inconsistency risks both under‑ and over‑use of these measures.

For Cardiff pupils, the presence of scanners and more frequent searches may either increase a sense of security or, for some, raise concerns about being treated as suspects rather than students. Community groups and charities such as StreetDoctors are likely to intensify outreach in high‑risk areas, trying to shift attitudes away from carrying weapons while schools and police focus on enforcement and safety.

For parents and local residents, the published FoI figures may heighten awareness of the scale of the weapons issue, leading to more public debate about how Cardiff and Wales balance school safety with students’ rights and mental‑health support. Over time, the effectiveness of Cardiff’s approach may be measured not only by how many weapons are found in searches, but by whether the number of incidents involving pupils with weapons actually declines.
