A teenage boy has been charged with murder after last Friday night's fatal Melbourne stabbing.
The South Yarra teenager, aged 15, was arrested on Friday morning and charged with one count of murder.
He faced a children's court and was remanded in custody.
A 40-year-old man from nearby Prahran was stabbed on Malvern Rd in South Yarra after 11pm last Friday.
He was rushed to hospital, but later died.
Police also again urged the rider of a motorised scooter and driver of a white van to come forward.
CCTV video released earlier this week showed the scooter hitting a person, who police say is the alleged killer.
The van was seen driving past the victim and his killer during the incident.
