An investigation has been launched into whether police acted properly in a car chase that ended with two men being injured.
Police watchdog, the Independent Police Complaints Commission (IPCC), will head the inquiry into the accident which happened last week.
Officers with South Wales Police were chasing a black Ford Fiesta on the A4058 in Pentre, in the South Wales valleys, on October 10.
The car lost control and hit a Vauxhall Corsa injuring the male driver, 22, and the 20-year-old female passenger.
Both were taken to the Royal Glamorgan Hospital, in Llantrisant. The driver remains in a stable condition.
"I hope that the young man seriously injured in this incident recovers from his injuries," said Tom Davies, IPCC Commissioner for Wales.
"This pursuit happened in a residential area and our investigation will look at whether it was carried out properly.
"There are detailed policies and procedures for police pursuits to ensure that they are carried out as safely as possible. Our investigators will look at what happened in this case and we will report our findings in due course."
The male driver of the Ford Fiesta was arrested for taking a car without the owner's consent, drugs offences and dangerous driving.
