A man injured in a Collingwood brawl has not had his leg amputated, according to Victoria Police, who have backtracked after previously saying he had lost his leg.

It’s understood the 18-year-old Fitzroy pedestrian, David Bilal, who was struck by a vehicle during the early morning melee is now in a serious condition in hospital and that his family is furious at the incorrect release of information.

The urgent correction is the latest in a series of errors made by the force within a 48-hour period surrounding the violent street brawl and comes as it reels from tough scrutiny over its response.

Hours after the correction was made, Victoria Police announced it had instigated a "comprehensive" investigation into the brawl.
