Dyfed-Powys Police in Wales said Friday a cyberattack affecting the force disrupted some non-emergency systems and may have compromised staff information.

The force said it identified the incident earlier this month. It has found no evidence that information belonging to members of the public was affected.

The police are still investigating whether information involving employees was accessed or compromised, a spokesperson said.

Dyfed-Powys Police covers southwest Wales and has more than 2,000 officers and staff. Tarian, the regional organized crime unit for southern Wales, is leading the investigation with support from cybersecurity specialists.

Police did not say how the breach occurred or what staff data may have been involved. No group had claimed responsibility as of publication.

“We understand the potential concern this may cause,” a spokesperson said, adding that the force was taking steps to protect its information and systems.

They said further updates would be provided when available.
