A murder investigation is under way after a woman's body was discovered in a river in Powys.
Police said the body of a 34-year-old was discovered in the River Severn outside Llanidloes, mid Wales, at around 4pm on Sunday.
A 46-year-old man was arrested on suspicion of murder later that day and remains in police custody.
Officers are appealing for any witnesses or anyone who has dashcam footage of a man and a woman in Llanidloes on Saturday or Sunday to come forward.
They are also interested in speaking with anyone who may have seen the man and woman on the A470 between Llanidloes and Dolwen on those days.
Police said the woman was wearing a grey top, dark trousers and white trainers. She was described as white, 5ft 4ins tall, of small build, and with very long dreadlocks.
The man has been described as approximately 6ft tall, of stocky build, and with dreadlocks and a dark coloured bandana.
Dyfed-Powys Police said he was wearing a short sleeve, high visibility jacket, t-shirt, shorts and light-coloured trainers.
He had a black bag with a single strap and police said he also had a small, dark-coloured dog with him.
Officers are also keen to speak with the person who gave the man and his dog a lift between Welshpool and Shrewsbury.
The force said he was dropped off near the Dinky's Dinahs layby in Shrewsbury on Sunday.
Police are not currently looking for anyone else as part of the investigation.
