A 20-year-old man has been arrested on suspicion of causing death by dangerous driving after a crash in Rhondda Cynon Taf in which two passengers died.
A man, 25, and woman, 23, died in the single-vehicle crash on the A4093 at Gilfach Goch at about 10:30 BST on Saturday.
A BMW 1 Series convertible was going from Hendreforgan towards Tonyrefail when it left the road, said police.
They said people in other vehicles in the area might may have seen the crash.
Officers have viewed CCTV footage and said a silver Volkswagen Passat and what they thought was a dark Renault Clio had been travelling from Gilfach Goch to Tonyrefail behind a bus.
Travelling in the opposite direction, again behind a bus, was what was believed to be a dark Hyundai Santa Fe, a silver Citroen Picasso, a white Mercedes C Class estate, a black Volkswagen Beetle and a silver Vauxhall Vectra.
The BMW had travelled through the village of Gilfach Goch along High Street and Cambrian Avenue before joining the A4093 towards Tonyrefail.
It had travelled past Hendreforgan when it left the road.
Anyone who witnessed the crash, or the car in the hours leading up to it, is asked to contact police on 101 quoting incident number 1400198704 or people can call Crimestoppers anonymously on 0800 555 111.
A South Wales Police official said next of kin of the people who died have been informed and were being supported by family liaison officers.
