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.
