A man is being questioned by police after handing himself in following a hit-and-run accident in which two cyclists were killed.
Ross Simons, 32, and his wife Clare Simons, 30, who were believed to have been on a tandem bicycle, were struck and killed before the driver of a Citroen car fled the scene in Hanham, near Bristol.
A spokeswoman for Avon and Somerset Police said: "A 38-year-old man who left the scene of the collision has handed himself in at a police station and has been arrested.
"The road currently remains closed and investigations continue."
Paramedics attended the scene on Sunday afternoon to find the man and woman had suffered fatal injuries.
"We took the call at 4pm reporting that a car hit two cyclists, a male and a female," a spokeswoman for Great Western Ambulance Service said.
"We sent an ambulance, paramedics, a rapid response vehicle and had an officer at the scene to liaise with the other services.
"But unfortunately both the patients were beyond help at the scene."
Police are appealing for anyone who witnessed the collision to contact them on 101.
