It is believed the man is linked to a property deal Bao, who worked as a real estate agent for Harcourts, was negotiating.
Stuff can reveal Bao acted as the agent for the buyer of the same property the alleged kidnapper lives at in Bryndwr, and completed the sale in June.
A neighbour said a lovely couple lived there before, but it since “became sketchy”, with security cameras put up on the house
The new owner of the Bryndwr property, who lives there with his wife and child, said he and Bao’s alleged kidnapper worked together at a factory.
The accused asked him if he had a room to rent, and moved in about a month ago.
The property owner said Bao was the real estate agent who helped him buy the Bryndwr home. He had not had any contact with her since the deal was completed in June.
On Thursday, after learning Bao was missing, the property owner said he shared a post on social media appealing for information about her whereabouts.
He worked late on Friday night, and did not see the accused.
The man said he was exhausted, and would not say if he had spoken to police.
He said he had no idea the accused had booked tickets to China.
