The Melbourne man wanted over the disappearance of his Chinese-Australian partner has been arrested after allegedly trying to avoid police.
Ju “Kelly” Zhang, a 33-year-old mother, was last seen leaving her home on Winchester Ave at Epping in Melbourne’s outer north on Monday afternoon.
A friend reported her missing to police on Tuesday evening.
Ms Zhang was in a relationship with Doncaster man Joon Seong Tan, 35, with police saying they had been unable to locate or make contact with him since Thursday.
“We believe that he is actively avoiding police contact,” Missing Person Squad detective inspector Andrew Stamper told reporters on Saturday.
He was arrested in Doncaster on Sunday afternoon and is now assisting police with their investigation.
Ms Zhang was wearing a pink pyjama top, shorts and no shoes when she disappeared, leaving her eight-year-old son behind.
All of her family lives in China and her former husband, the child’s father, is looking after the boy.
“There are no circumstances, as far as we have been told, that Kelly would ever leave her son,” Det Insp Stamper said.
Det Insp Stamper had earlier said there was a possibility he had gone interstate in his black Mazda station wagon.
“He’s provided us with a version of an account of his last sighting of Kelly,” he said.
“He has told us she went out for a walk and didn’t come back.
“We say that is a very unlikely scenario bearing in mind that her eight-year-old son was in the house.
“The information we have is she would not have left him by himself with someone that wasn’t a family member.”
Ms Zhang’s disappearance has sparked a “great deal of talk” within the Chinese-Australian community on social media platforms including WeChat, Det Insp Stamper said.
Police have been unable to locate Ms Zhang’s mobile phone and foul play is an active line of inquiry.
“We hope that Kelly might contact us and tell us where she is,” Det Insp Stamper said.
“There may be some other explanation. That would be our sincere hope. But we do hold grave concerns for her welfare.”
Anyone with information about Mz Zhang’s disappearance is urged to contact triple zero or Crime Stoppers.
