The Metropolitan Police said one of the four pedestrians hit by a car on Christmas Day in London’s West End has died in hospital.
Aidan Chapman, 25, was seriously injured in the incident in Shaftesbury Avenue and died on New Year’s Eve.
Police said they are treating the death as homicide and a post-mortem examination will take place in due course.
In a tribute, his parents said: “The loss of our beautiful son is a parent’s worst nightmare, we are utterly devastated with the loss of Aidan, he enriched everyone’s lives.
“He was a loving, kind, funny soul and the world is a darker place without him.
“We, his parents, have lost the best part of ourselves.”
Anthony Gilheaney, 30, of Harlow in Essex, appeared in court last week charged with four counts of attempted murder and a number of driving offences in relation to the crash and will next appear at the Old Bailey on January 24.
The charges will be reviewed following the death of Mr Chapman, the Met said.
