A 35-year-old hairdresser was allegedly stabbed to death by her husband inside their apartment because he was upset she had converted to Christianity.

Amir Darbanou was charged with the murder of his wife Nasrin Abek after her body was found inside their apartment in the affluent suburb of Potts Point on Thursday.

The 42-year-old, from Iran, was allegedly enraged that Ms Abek had recently converted to Christianity and killed the hairdresser in a frenzied knife attack on Wednesday night, the Sydney Morning Herald reported.

Police made the gruesome discovery when they forced entry into the couple's home at about 6.20am on Thursday after Ms Abek's father raised concerns for her welfare.

Mr Darbanou had allegedly called his father-in-law in Iran to tell him Ms Abek was dead on Wednesday night and was arrested after her body was found the next day.

Ms Abek's father said his heartache over her death had been made worse by the fact he had to contact police 'several times' before they would act.

He said he became concerned when he had not heard from her for a 'prolonged period', Nine News reported.

The 42-year-old, who reportedly 'stalked' his wife, did not enter a plea or apply for bail when he appeared in Sydney's Central Local Court on Friday.

Police said there was no known history of domestic violence between the couple, who had been living in Australia for four years on bridging visas, but neighbours had reported hearing screaming coming from the apartment on Wednesday night.

One neighbour, who did not want to be identified, said she heard blood-chilling screams come from the apartment at about 4.40pm, but only silence after.

She overheard detectives saying there was 'a lot of blood splatter' inside the apartment as they scoured the front yard for the murder weapon.

Superintendent Mick Fitzgerald said officers believe they recovered the knife allegedly used to kill Ms Abek during a search of a nearby garbage tip, but at this stage of the investigation it was 'too early to tell'.
