Two cyclists who were killed in an alleged hit-and-run incident near Bristol have been named as a married couple.
Ross Simons, 32, and his 30-year-old wife Clare died in the crash in Hanham on Sunday.
A 38-year-old man remains in police custody having been arrested on suspicion of causing death by dangerous driving, Avon and Somerset Police said.
A 35-year-old woman has also been arrested on suspicion of dangerous driving.
The matter has been referred to the Independent Police Complaints Commission, the force confirmed.
It is understood this relates to the fact that police were in pursuit of a car before the fatal collision.
Avon and Somerset Police said that shortly before 4pm on Sunday, an officer's attention was drawn to a Citroen Picasso travelling along Lower Hanham Road at speed.
The officer indicated to the car to stop but it made off.
"The officer began to follow the car but it was lost to sight almost immediately," a force spokeswoman said.
"Very shortly afterwards the car struck another vehicle and then collided with two cyclists on a tandem bicycle."
