The police questioned a 31-year-old man after a boy was killed in a collision.
The 11-year-old died in hospital after being treated at the site of the crash in Beswick, Manchester.
A gray Volkswagen Golf was supposed to have been involved in the collision on Albert Street shortly after 6:10 PM on Saturday night.
The Greater Manchester police said the car had been left at the spot. Officers call on witnesses.
The police said the man was later at a police station and was arrested on suspicion of death by dangerous driving.
He remains in custody for questioning.
Albert Street is closed between Charlestown Street and Darley Street. Doric Close is also closed while research work is being carried out.
PC Karl Horner of GMP's Serious Collision Investigation Unit said: "This was a tragic incident in which a young boy lost his life, and my thoughts are with his family in this incredibly difficult time.
"We have a man in custody, but our investigations continue as we work to determine the full conditions that led to this collision.
"If you think you've seen the driver of the gray VW Golf around the time of the crash, or if you've seen what happened, please contact us as soon as possible.
