The owner of a Western Sydney pizza shop fatally stabbed in the chest has been identified as Sonmez Alagoz after police arrested six teenagers over the incident.
Emergency services were called to The Pizza Stop on the Great Western Highway, near Kingswood Train Station, about 10.20pm on Tuesday after Mr Alagoz, 58, was found with a single stab wound to his chest.
NSW Ambulance paramedics treated him man at the restaurant before he was taken to Westmead Hospital, where he died.
Superintendent Trent King, Commander of the Nepean Police Area, said four males and two females, aged between 14 and 19, were assisting police with their inquiries.
No charges have been laid.
A nearby business owner told Daily Mail Australia his passing was a ‘great shame’.
‘I don’t know why it could happen to him,’ he said.
Locals took to social media to remember Mr Alagoz’s kindness over the years.
‘He was such a lovely man. He and, I believe, his wife used to give lollies to my kids while waiting for our pizzas,’ one woman wrote online.
‘This is a putrid act.’

Police arrested six teenagers over a shocking incident which saw the business owner killed
‘Such a beautiful lovely man, always working hard, so friendly,’ another woman added.
‘He was so lovely,’ another said.
‘That man works so hard,’ one local man said, ‘he just came back from holidays … Cowards’.
‘Condolences to Tia and [the] family, my heart goes out to you all. Beautiful family and he will be sadly missed by all who knew him,’ a woman added.
Supt King said Mr Alagoz had sustained a ‘gruesome’ injury.
‘This was a gentleman that was going about his business, running his business, within the local area and certainly didn’t deserve what occurred,’ he said.
‘My understanding is that this gentleman was very closely connected to this community for a very long time. I certainly empathise with every person that knows him, and his family. Everything was done that could possibly be done.’
Supt King said police were ‘leaving no stones unturned’ and were investigating multiple lines of inquiry.
Investigators will work to establish why the group of teenagers, who were previously known to police, were near the store on Tuesday night.

‘Initial investigations indicated those teenagers were in and around the vicinity at the time. They are known to police [but] weren’t dining in the restaurant,’ Supt King said.
Several police officers were seen speaking to witnesses outside the store which was cordoned off with police tape overnight.
The crime scene was then extended to cover a row of stores beside The Pizza Stop, extending about 100metres down the road.
Police laid yellow crime scene cones around the pizza store and taped off a parking lot across the road on Wednesday morning.
Drivers on the Great Western Highway saw detectives scouring the nearby area and talking to passersby.
Police have appealed for anyone with information about the stabbing to contact Crime Stoppers on 1800 333 000 or online.
