A number of crime scenes have been established and police are investigating. The attackers remain at large.
A spokeswoman for NSW Police said officers were yet to speak to the victim but there was no information to suggest the stabbing was anything other than a random attack.
NSW Police Superintendent Stephen Egginton described the incident as “pretty brazen and bold behaviour from a number of offenders.”
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
