Police are attempting to track down a hit-and-run driver who knocked down and killed a father and his teenage son while they were out cycling.
Dean Jones, 45, and Lewis Daines, 16, were killed on Royston Road, Cudworth, Barnsley, at around 9.20pm on 20 January.
Paramedics attempted to revive the pair when they arrived but they both died at the scene.
The driver who ran into them failed to stop and drove off after the crash.
South Yorkshire Police said a 37-year-old man who was arrested on suspicion of causing death by dangerous driving has since been released with no further action.
Officers are now appealing for information that will help find the driver, who is thought to have been driving a red Volkswagen Golf, which was later found abandoned in the village of Shafton, around half a mile away.
Lewis' cousin, Samantha Earnshaw, paid tribute to the teenager, describing him as "the most loving boy you could meet".
She added: "It's such a huge loss. I'd do anything thing to have him back here with us – anything."
South Yorkshire Police said in a statement: "A 37-year-old man was arrested on suspicion of causing death by dangerous driving. He has since been released with no further action, after being eliminated from our enquiries.
