Arrests over Sam Walker 2003 Chorlton hit and run death
Three people have been arrested over the death of a five-year-old boy in a hit and run in Greater Manchester more than a decade ago.
The arrests follow a public appeal for information on the 10th anniversary of the death of Sam Walker in Chorlton.
A man, 33, was arrested on suspicion of causing death by dangerous driving.
A 31-year-old man is suspected of perverting the course of justice and perjury, and a woman, 56, was arrested on suspicion of perjury.
After the appeal for information earlier this year a "significant person" came forward with information, police said.
Officers have appealed for the same person to contact them again, as it is believed they hold vital information. A £20,000 reward is on offer.
Sgt Lee Westhead said: "It is clear that the community of Chorlton-cum-Hardy want to end the suffering of Samuel's family.
"They have endured enough. The cowards involved have hidden for too long and it is time to end this."
Sam was crossing Hardy Lane with his mother, sister and cousin, at 13:00 GMT on 9 February 2003 when he was hit by a silver Mitsubishi Gallant, registration J722BUY.
The car was abandoned on a footpath running off Riverside Avenue and the driver seen running away across Princess Parkway.
He was described as a black man aged between 18 and 21.
