The husband and brother of Indian national Prabha Arun Kumar, who was stabbed to death in Sydney, have made an emotional appeal to Australian authorities to find her killer and bring him to justice.
Prabha Kumar, 41, was knifed in a brutal attack while speaking by phone to husband G Arun Kumar in India on Saturday night.
"I cannot describe to you the pain I presently feel," the husband told reporters after rushing to Sydney.
"My wife was a most caring and beautiful soul. I want whoever killed my gorgeous wife to be brought to justice."
Kumar's husband flew to Australia on Monday from India, where both he and their nine-year-old daughter live.
His wife's brother Shankar Shetty also attended a police press conference to make a public appeal for information about the murder, with no suspects so far identified.
"I'm still coming to terms that I've lost my sister," Shetty said. "She will never see her daughter grow up."
"You have taken my sister's life, please step forward and get help and get your life back," he said.
"Nobody deserved to have anyone from their family taken away from them in these horrific circumstances," he said, adding, "the pain I have felt since (her death) has been unimaginable."
A task force has been set up to investigate the murder, which happened just a few hundred metres from her flat, but no motive has been established or arrests made, police said.
"There was no evidence of any sexual assault," a police spokesperson said, reiterating that there was also no evidence that it was racially motivated.
Police have interviewed several witnesses since the attack on her in a park in Sydney on Saturday.
Police have also released the CCTV footage of Prabha walking from the Parramatta train station just before she was fatally stabbed and appealed to people for information to crack the baffling case.
Several hundred mourners held a candlelight vigil in western Sydney on Wednesday night for the dead woman, who had been due to return home to India in April.
