Parramatta police Superintendent Robert Redfern said officers were still looking for another teenage male and a small group of teenage girls in relation to the stabbing death of Patrick Crowe on the weekend.
In a press conference about the four people who had been arrested over the stabbing of the 22-year-old, held this morning, Superintendent Redfern said officers wanted to speak to another teenage male aged in his late teens.
Police are also looking for three females aged between 15 and 17 who may be able to help with their inquires. Two of the girls were described as Pacific Islander in appearance, while the other was described as Caucasian, Superintendent redfern said.
Asked whether Mr Crowe was involved in an argument with the group of girls in a nightclub before the altercation on Argyle Street, which led to his stabbing were not answered by Superintendent Redfern.
Superintendent Redfern said he had broken the news of the arrests to Mr Crowe’s family.
''Nothing can bring Patrick Crowe back, and I have just finished speaking to the family, but I hope making these arrests brings them some comfort,'' he said.
A 21-year-old man has been charged with murder over the incident and another three males, aged 18, 16 and 15, have been charged in relation to it.
While he didn’t comment at length about the young age of those involved, Superintendent Redfern said any incident which ends in murder is concerning for public safety.
