Melbourne Crime Investigation Unit detectives are continuing to appeal for information following a stabbing in Melbourne’s CBD.

It is understood a group of five male youths, armed with weapons, were involved in an altercation with another boy about 3.45pm on October 21 last year.

The boy was stabbed during the incident and was taken to hospital with non-life-threatening injuries.

Police were told five male offenders fled the scene on foot.

After an extensive investigation, police would like to speak to anyone who may have witnessed the incident.

Investigators have released an image of five youths they believe may be able to assist with their enquiries.
