Woman critical after violent stabbing at North Melbourne

A woman has been critically injured following a vicious stabbing and robbery at North Melbourne.

She is believed to be in her 30s and was riding a bike along Harker Street about 2.30am on Wednesday when she was approached by two males and a female.

One of the males produced a knife and made demands for her bike and personal belongings.

The victim was then slashed on her face, upper arms, torso, and neck before the offenders fled on foot.

She managed to get to Flemington Road where she flagged down a passer-by who called police.

She was taken to hospital where she remains in a critical but stable condition.

Police are keen to speak to anyone who may have seen two males and a female, perceived to be of African appearance, that were in the vicinity of Harker Street about 2.30am this morning.

Anyone with information about the incident is urged to contact Crime Stoppers on 1800 333 000 or at www.crimestoppersvic.com.au
