Sergeant Lee Westhead is part of the team investigating the death of Sam Walker who was knocked down and killed ten years ago in Chorlton.
Police investigating the death of a five-year-old boy, who was knocked down and killed by a car in Chorlton more than 10 years ago, have made three arrests. It follows a public appeal for information earlier this year on the 10th anniversary of Sam Walker's death.
A 33-year-old man was arrested on suspicion of causing death by dangerous driving, a 31-year-old man was arrested on suspicion of perverting the course of justice and perjury and a 56-year-old woman was arrested on suspicion of perjury.
All three remain in police custody for questioning.
Sam Walker was hit and killed 10 years ago on Hardy Lane in Chorlton. He'd been out buying sweets with his mum and sister. Today would have been his 16th birthday.
Police are back out in the area and have parked a replica of the car that killed the 5 year old on the street in happened.
Officers hope it will jog people's memories and appeal to the driver to give himself up. A £20,000 reward has also been offered for information that leads to a conviction.
