A man is being questioned after a six-year-old boy was knocked down and killed by a motorist.
West Yorkshire Police on Tuesday arrested a 21-year-old from Huddersfield on suspicion of causing death by dangerous driving.
He was being interviewed in connection with the death of Owen Wightman, who was hit by a car while out playing with his seven-year-old friend close to his home in Wakefield, West Yorkshire, on Saturday.
Owen was hit as he crossed the busy Fishpond Road at lunchtime on Saturday.
Police said a light blue or grey hatchback driven by a lone white man, probably in his 20s, failed to stop at the scene. But the car did stop about 100 yards further along the road after taking a left turn into Haveroid Lane, police said.
The driver was seen inspecting the front of the car for damage.
A team of detectives have been scrutinising CCTV footage from a passing bus which captured the car involved.
Police said they have had a "good response" to appeals for help.
Owen's parents, Joanne, 33, and Neil, 31, said they had lost their "baby" and appealed for someone to come forward so they could "lay him to rest".
A statement said: "He was a perfect little man who was taken from us - just perfect in every way. He walked into a room and lit it up. He was our bundle of joy and our little ray of sunshine."
