A woman has been stabbed to death in a Sydney park shortly after telling her husband that a suspicious man was following her.
Prabha Arun Kumar was taking a shortcut through Parramatta Park at around 9.30pm on Saturday when she was murdered in what police say was a "horrific" attack.
She was just 300 metres from home when the killer stabbed her repeatedly in the neck.
Mrs Kumar was found by a passer-by but died in hospital from massive blood loss.
"She was walking while talking to [her husband] on the phone when she said that a suspicious-looking man was following her," brother-in-law Thrijesh Jayachandra told Indian newspaper The Hindu.
"The next moment he heard her scream for help and then plead with the man not to harm her and take all her belongings if he wanted.
"Seconds later, he heard her scream and say she was stabbed."
Police have released CCTV of Mrs Kumar walking from Parramatta Railway Station.
"Here we have an Indian national who has been in the country for some time, going about her business and ends up being killed in a very vicious way," said New South Wales homicide squad commander Michael Willing.
"It's a horrific crime. It's a very, very disturbing crime.
"We think that she sustained a number of injuries to the neck area with what we believe is a sharp-edged weapon."
Commander Willing said there was nothing to suggest the murder was racially motivated but that they were examining all possibilities.
Mrs Kumar, a 41-year-old IT worker, was planning to move back to India in April to be reunited with her nine-year-old daughter.
Her husband has now flown to Australia to help with the investigation.
