The family of a 47-year-old who died following an incident in Llanelli on Saturday morning have paid tribute to him, saying he was a "great role model for his grandchildren."
Andre Yan Irwin was found injured in Coleshill Terrace and died a short time afterwards in hospital.
We are devastated at the sudden and tragic loss of a brilliant father, son, grandfather and fiancé.
Police said they are now treating this as a murder investigation.
A 42-year-old was arrested at the scene and is currently in custody.
Our thoughts are with the family of Mr Irwin, who we are supporting at this sad time.
