Seven members of staff at Cardiff Council have been arrested on suspicion of fraud, the council has confirmed.

The police arrested eight people on Wednesday as part of a fraud investigation. Seven of the suspects worked for Cardiff Council’s waste management service.

It is understood all eight have been released on bail.

A council spokesperson has confirmed that the authority is working with South Wales Police while the investigation continues.

Responding to the news, the Cardiff Liberal Democrats commented on Facebook that they were ‘concerned’.

‘For now, as the investigation is a police matter and at an early stage, it would be inappropriate to comment further,’ they wrote.

‘We are confident the council will act with transparency in providing the police and, in due course, the public with any information they need.’
