A man who allegedly stabbed his wife to death in western Sydney gave a "chilling" account to police, according to the magistrate who's refused the 33-year-old accused bail.
Bangladeshi Shahab Ahmed appeared at Parramatta Local Court via video-link on Monday charged with murdering his 29-year-old wife, Khondkar Faihi Elahi, on Saturday at their Parramatta unit.
Police will allege Ahmed killed Ms Elahi after learning she was having an affair.
Magistrate Gary Still told the court "the account that he gave to police is chilling".
He referred to court documents stating Ahmed had made multiple threats to Ms Elahi at their unit before her death and that he stabbed her repeatedly with a knife "including in the back".
Police said Ms Elahi was found stabbed in the chest at the couple's unit and later died in Westmead Hospital.
Ahmed is alleged to have called triple-zero after the incident and stayed in the unit until police and paramedics arrived.
His lawyer, Zemarai Khatiz, on Monday told the court this meant his client should be bailed.
"He remained there, he called triple-zero ... if he had any ideas of absconding he would have," Mr Khatiz said.
He proposed Ahmed be subject to strict house arrests so he could leave for work and confer with his lawyers.
But Mr Still rejected the proposal saying nothing he'd heard "persuades me that he can show why his detention isn't justified".
Outside court, Mr Khatiz said he was disappointed with the result, and Ahmed was likely to be very upset.
Mr Khatiz on Sunday revealed his client had been distressed and emotional since the incident.
"The deceased was having an affair. He found out about it and the relationship came to a very tragic end," he told reporters outside court.
Mr Khatiz said his client intended to fight the charge.
Ahmed is expected to appear again via video-link link on April 12.
