A man has been charged with murder after the bodies of an elderly couple were found inside a takeaway shop in Sydney's west.
Officers were called to the shop on Oxford Street, Cambridge Park, near Penrith, after reports of an assault about 9.40am on Saturday.
The couple, aged in their 60s, were found with "significant injuries" after a member of the public alerted police.
A 31-year-old man was arrested at a home at Canley Heights, 30km west of the CBD, at about 12.30am on Sunday.
All three people involved were known to each other, police will allege.
The man was taken to Fairfield Police Station where he was charged with two counts of murder.
He was refused bail to appear at Parramatta Local Court later on Sunday.
Detective Superintendent Michael Cantrell said officers arrived to a "confronting scene".
"Obviously the welfare of our officers is being addressed, and we have systems in place for that," he told reporters in Sydney on Saturday.
Supt Cantrell said footage possibly relating to the incident has been posted on social media.
"I'm aware that there is footage around, and it's been through social media, and we're looking into that and looking at all lines of inquiry," he said.
