DYFED Powys Police have made a further appeal for witnesses following a fatal crash on the A48 at the Cwmgwili junction last month.

Tragic Colin James of Cross Hands was killed in the three-vehicle pile-up which happened at around 11:15pm on Friday, April 10 on the eastbound carriageway.

Officers say the vehicles involved were a silver Renault Clio, a grey Seat Ibiza and a red Renault Clio.

They are keen to speak to the owner or driver of a white Toyota MR2 who was in the area at the time and could be a possible key witness to the incident.

"We are urging this possible significant witness to help us with the investigation," said a spokeswoman.

"If you are the owner or driver of the vehicle, or you have any information that you think may assist please contact Ammanford police on 101 or Crimestoppers on 0800 555111.
