Six teenagers have been arrested as police probe the motive behind a fatal stabbing at Kingswood last night.
Sonmez Alagoz, the owner of The Pizza Stop at Kingswood, suffered a single stab wound just after 10.00pm on Tuesday night.
58-year-old Alagoz was transported to Westmead Hospital where he later succumbed to his injuries shortly after 12.30am on Wednesday morning.
Nepean Police Area Commander Detective Superintendent Trent King confirmed that police have arrested six teenagers, four boys and two girls, in connection with the incident.
No charges have been laid.
“There are six teenagers at the moment that have been arrested and are in custody within Nepean Police Area Command,” King said.

“They range from 14-year-olds to a 19-year-old.
“At this stage is very early in the investigation and they are people of interest that we are speaking to in relation to the matter.”
Strike Force Narrira has been established to continue investigations and is comprised of Nepean Detectives, State Crime Homicide Squad as well as other Northwest Metropolitan resources.
“We are leaving no stone unturned in relation to this initial investigation… We are certainly exploring every avenue in relation to the information that we need to finalise this matter quickly….” King said.
“If anybody out there does have any information that can provide further assistance to the investigation, contact St Marys Police or crime stoppers.”
Police have confirmed that the teenagers have been cooperating with the investigation and indicated they were not dining at the shop before the incident.
Members of the public placed numerous triple zero calls and attempted to assist the man before police arrived.
“The Great Western Highway is a very busy road, and I can say that members of the public provided information to triple zero very quickly and the response to the scene was very quick as well,” King said.

“I would suggest that everything was done that could possibly be done to try and save the gentleman. Unfortunately, the wound was a fatal wound from the moment it occurred.”
Alagoz is a well-respected member of the local community and police have labelled his alleged murder a “tragedy”. He was known to many as simply ‘John’.
“My understanding is that this gentleman was very very closely connected to this community for a very long period of time, including owning this business for over 14 years and being a member of the Penrith community for over 50,” King said.
“This is an absolute tragedy; there’s no other way of describing it and I certainly empathise with every person that knows him and indeed his family.”
Alagoz’s family was notified and attended the police station overnight.
“They are obviously distraught in relation to what has occurred,” King said.

“This is a tragedy that we can’t ignore and certainly we’re putting every effort forward in relation to trying to resolve this matter as quickly as possible both for the community and the family’s sake.”
Investigations continue under Strike Force Narrira.
