Police are continuing to make enquiries into the disappearance of two young men in Sydney, who haven't been seen since Monday.
Bloodied possessions belonging to Luke Davies, 29, and Jesse Baird, 26, were found in a skip bin in Cronulla on Wednesday, 30 kilometres away from the pair's home in Paddington.
It was that discovery that alerted police to their disappearance, with more blood found inside the home.
Their disappearance is being described as "suspicious" and detectives say they hold "grave concerns".
A phone, keys, credit cards and an expensive watch were found in the skip bin.
After the discovery, police immediately searched Baird's home in Paddington.
"There has been some sort of incident that had more than likely occurred at the Paddington address," Detective Superintendent Jodi Radmore said on Thursday.
Witnesses have described hearing a verbal argument at the property on Monday morning.
A second suburban Sydney property was searched by the NSW Police Force on Friday morning.
The Balmain property is believed to be linked to Sydney police officer Constable Beau Lamarre, who is reportedly the former boyfriend of Baird and has also disappeared.
CCTV footage shows the couple walking outside Baird's property, before a white van is later seen driving past. Police believe the van is linked to the missing officer.
Det Insp Radmore said they had been looking for a third person who may be able to assist with the investigation.
She said they held "grave concerns" for the missing men.
Baird worked at Channel 10 for about seven years, with his LinkedIn profile indicating he left the network in January.
Davies has most recently worked as a flight attendant with Qantas.
Anyone with information is being urged to contact police.
