Two cyclists who were killed in an alleged hit-and-run incident have been named as a married couple.

Ross Simons, 34, and his 30-year-old wife Clare died in the crash in Hanham, near Bristol, 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."

Inspector Frazer Davey, from the Collision Investigation Team, said: "Following investigations overnight, the circumstances of this collision have become much clearer. However, I would appeal to anyone who witnessed this incident or saw this car in the area shortly before the collision to come forward and contact us."

Mr and Mrs Simons both died at the scene as a result of their injuries. The man who was in custody handed himself in to police hours after the crash, having allegedly fled the scene.

Speaking after laying flowers family friend Steve Camm said: "There were like two peas in a pod. They were never apart. They could never do enough for anybody. They were caring people."

Fighting back tears, Mr Camm said Mr and Mrs Simons had been married for about 18 months. "They always did random stuff. You could never stop them from having fun. It's devastating," he said.
