A man has been arrested in connection with a fatal hit-and-run crash in West Yorkshire.
Stephen Wood, 39, died when he was hit by three cars while walking on the A65 Skipton Road, near Ilkley, just after midnight on Sunday.
West Yorkshire Police said two of the three cars which hit Mr Wood failed to stop at the scene.
Officers arrested a 38-year-old man on Sunday on suspicion of causing death by careless driving.
He was later released on bail.
Det Sgt Carole Clayton, of West Yorkshire Police, said: "We still need to trace the driver of another vehicle which may have collided with Stephen before driving off.
"I would urge anyone with any information to contact us immediately."
Police have released details of two other cars they want to trace, as the drivers could be witnesses.
Det Sgt Clayton said the vehicles stopped at the scene but left before officers could speak to them.
She said: "One is a blue-coloured VW Passat and the other is a small silver 4x4-type vehicle.
"The drivers of these vehicles are potential witnesses and may have seen something that could help the investigation."
Police said Mr Wood, who is from the Ilkley area, had been drinking in the Vaults public house earlier in the evening before walking along the A65.
