Police have been given more time to question a man over a domestic incident which left a woman in a critical condition.
It occurred at about 17:45 BST on Thursday at a property in Graig Avenue, Llanelli, Carmarthenshire.
A 19-year-old woman remains in a critical condition in hospital.
A 21-year-old man remains in custody after Llanelli Magistrates' Court approved a warrant for further detention.
Dyfed-Powys Police said Graig Avenue, which was closed to allow police to investigate, has now reopened - although one property remains cordoned off.
Officers will continue to carry out house-to-house enquiries. Police said they are not looking for anyone else in connection with the incident.
