A Plaid Cymru MP has been arrested on suspicion of assault.
Jonathan Edwards, member for Carmarthen East and Dinefwr, has been expelled from the party after being detained by police on Wednesday.
Officers with the Dyfed-Powys force confirmed a 44-year-old man from Ammanford had been arrested and released on bail pending investigation. They said they would not be releasing any further information about the inquiry.
Sharing the full story, not just the headlines
Plaid Cymru said it had withdrawn the whip from Mr Edwards after being made aware of the investigation.
It means the father-of-two will now effectively sit in parliament as an independent.
A Plaid Cymru statement released early on Saturday morning said: “Jonathan Edwards MP was arrested following a report of an incident.
“The party whip has been withdrawn pending the conclusion of a police investigation.
“Mr Edwards has accepted this course of action and is complying fully with the police enquiries.
“It would be inappropriate for the party to comment further at this time.”
