Ten youths busted over Melbourne robbery

An 11-year-old boy is among a gang of youths who will soon face a children's court after allegedly assaulting and robbing a man along Southbank in Melbourne.

A 21-year-old man was walking along Southbank with a friend at 3.45am on Tuesday when they were allegedly set upon by a group of 10 children who stole a mobile phone and wallet from one of the men.

Two boys, aged 11 and 13, and three girls, aged 13 and 15, have been charged and bailed to face a children's court at a later date, while a 16-year-old Werribee girl will face court for a remand application.

Four others were released pending further inquiries.
