A relative has been arrested over the murder of an Australian-Pakistani family of five in Pakistan.
The family, believed to have once lived in Melbourne, was found dead on October 13 in their home in the capital Islamabad.
A nephew of the family, Sikander Zia, has been arrested and has confessed to killing the family with hired assassins, Fairfax Media reports.
He told Fairfax from his prison cell he was motivated by money.
"It was my plan I came up with 15 days ago,"he told The Age.
"I was facing financial crisis and this was the easiest solution to get money." Zia is expected to be charged with the murders of Amir Khan, his wife Nazia Amir and their three children, Romana, 17, Adam, 14, and seven-year-old Haider.
Police said the family had been strangled and three of six hired assassins were still on the run.
Zia said the seven-year-old was the last family member killed.
"I could not let him live, he knew me and we had played together, and he could identify me," he said.
Zia said if he faces court he will ask for the death penalty.
