Detective Leading Senior Constable Darren Paxton, of Frankston CIU, said the offender, possibly affected by alcohol, attempted to punch the victim to the head and made further demands for the keys in the confrontation on the footpath between Wells and Playne streets.
He then chased the victim out onto Nepean Hwy where “it was a miracle he was not hit by a passing car”, Detective Paxton said.
The offender, pictured, is described as Caucasian, late teens or early 20s, solid build, 178cm, long black wavy hair, wearing a dark coloured Adidas jacket, green cargo pants and runners.
Anyone with information is urged to call Crime Stoppers 1800 333 000.
