A woman who died after being hit by a car in Sheffield has been named by police following the arrest of a 12-year-old boy on suspicion of murder.

Marcia Grant, 60, was a “warm, loving and dedicated wife, mother, grandmother, sister and friend and a pillar of her community”, her family said.

Emergency crews were called to reports of a collision between a car and a woman in the Greenhill area of Sheffield at 7.10pm on Wednesday.

Ms Grant was pronounced dead at the scene.

The boy was found shortly afterwards and arrested on suspicion of murder as well as suspected possession of a knife.

Ms Grant’s family said her death “has already sent shockwaves through all who knew her or [were] lucky enough to be included in her orbit”.

“We ask for privacy at this time while further investigations are underway and the family try to come to terms with this enormous loss,” they added.

Detective Chief Inspector Andrea Bowell, from South Yorkshire Police, said: “This will be a deeply distressing time for the families of those involved in this incident, and I would ask their privacy is respected as they seek to understand what has happened.”
