A man has stolen a pair of shoes and then left his victim money during an armed robbery in Melbourne's central business district early this morning.
A 20-year-old Docklands man was using a public phone in Collins Street when he was approached by another man who asked him for his trainers.
After the Docklands man repeatedly refused to hand over his shoes, the second man produced a knife and forced him to take the trainers off.
The thief then left behind his own shoes and A$50 in the phone box before running off.
Police say the trainers are worth more than A$300.
