A 13-year-old boy has died after being hit by a car while out with his family.
West Midlands Police said Mason O'Grady was crossing Chester Road in Erdington, Birmingham, when he was hit by a black VW Polo just before 18:50 BST on Sunday.
He was taken to hospital where he later died.
The driver - a 28-year-old woman arrested on suspicion of causing death by dangerous driving and failing to stop - remains in police custody.
A tribute released by his family described Mason as a "kind, loving and genuine" boy with a "heart of gold".
It said: "He would do anything to make you smile and he brought happiness and joy to the life of everyone he met.
"Mason, we will love you always."
Hayley Myles, a friend of Mason's mother at Sutton Town Netball Club, described him as "a beautiful soul" who was always smiling.
"This is just awful," she said. "He was so lovely, funny, you never saw him in a bad mood."
Meanwhile, a fundraising page set up following his death has raised more than £6,000.
Det Sgt Alan Hands said: "This is a parent's worst nightmare and it's impossible to imagine their grief, but specialist officers will be supporting them as our investigation continues."
Anyone with information is asked to contact police on 101.
