The brawl unfolded just after 4pm yesterday at Bendigo Marketplace, sending the centre into lockdown.

Two are aged 17, one is 15 and one is 14.

"He was assaulted by the group of youths which resulted in him receiving kicks and punches and being stomped on," David Bowler from Victoria Police said.
