Police are investigating a fire at an abandoned property in Burry Port.
A call was made at around 1.20 am on Tuesday, (Nov 19) reporting that a detached house in Graig was well alight.
The house is not lived in and has sustained substantial fire damage.
There were no witnesses to indicate who has started the fire, but two people were seen running away from the scene.
Due to the temperature inside the building remaining high today, it has been unsafe for investigators to enter the building.
Anyone with information, or who saw a person or people acting suspiciously in the area between 12.30 am and 1.30 am is urged to contact the joint investigation unit at Llanelli Police Station.
