A "kind and caring" 11-year-old girl has died after she was hit by a car while crossing the road.
Ruby Cropper was walking with a friend on New Road in Bury at about 4.30pm on Monday when she was in a collision with a blue Suzuki Alto, a spokesman for Greater Manchester Police (GMP) said.
Police said the driver left the scene but a 35-year-old man contacted police a short time later and was arrested, before being released on bail pending further enquiries.
Ruby was taken to hospital where she passed away from her injuries.
In a statement released by police, Ruby's mother and two fathers said: "As Ruby was such a kind and caring person and always helped others she has continued to do this in organ donation.
"Ruby's legacy will live on and we have taken great comfort in this.
"Our family would urge anyone in these tragic circumstances to follow in Ruby's footsteps and be an organ donor.
We are all absolutely devastated and a part of us has died today too. Our lives will never be the same again.
