New South Wales police have launched a manhunt for Chamanjot Singh, 23, in connection with the murder of his wife, apparently six years elder to him. She was found dead in their home, her throat slit, it is reported.
The Sikh young man had moved to Australia from Punjab state about six to eight months ago and been living in Westmead for the last month.
He was last seen leaving the house wearing shorts, a white singlet and a pair of thongs.
"We understand that he is the husband of the deceased and we are very keen to speak to him about the circumstances surrounding her death," Assistant Police commissioner Dennis Clifford said this afternoon.
Mr Clifford could not say whether Mr Singh was armed but "we are still looking at the possibility of a weapon that was found at the scene being used to kill the young lady, but they're the sorts of issues we'd like to clarify by speaking to the young male".
"We believe that he is still in the Sydney area but may travel interstate so we're appealing to people not only in NSW but other states as well to keep a look out for this person, and if they have any idea of his whereabouts or anything that might assist police, can they please contact either Merrylands detectives or Crime Stoppers."
Mr Singh had been working at various jobs in Sydney since coming to Australia, while his wife, also an Indian national, had been studying.
The NSW police said on their website - Detectives are conducting inquiries into the suspicious death of a woman at Westmead, in Sydney's west, overnight.
Police from Holroyd Local Area Command attended a house in Houison Street shortly before midnight after receiving reports a woman had been injured in a domestic dispute.
Upon arrival, they located the woman - believed to be a 29-year-old Indian National - deceased.
She had sustained a knife wound to the throat.
A crime scene was secured and examined by local detectives and specialist forensics officers. State Crime Command's Homicide Squad has been briefed about the incident.
A canvass of the surrounding neighbourhood was conducted by general duties officers.
Police are now seeking public assistance to locate a man believed responsible for the woman's death.
