A man has been released without charge after a woman fell to her death from a seven-story apartment yesterday.

The man was arrested after the woman fell to her death from a Parramatta apartment complex in the early hours of Thursday morning.

He was questioned by an interpreter and released without charges today.

Police received a triple-zero call from the Parramatta address two hours before the woman’s fatal fall.

Detective Superintendent Barry Vincent said the initial triple-zero call was made at about 11.45pm on Wednesday but there was no communication from the caller, although “raised voices” were reported.

Triple zero attempted to return the call twice but did not make contact.

NSW Police called the same number at 11.47pm and spoke to a man who confirmed his name and address, Vincent said, and police told him they would attend the premises but did not give a time.

Police were attending other calls for assistance en route to the address when they received a call from somebody standing in the street on River Road in Parramatta who said they saw a woman hanging from the seventh-floor balcony of a high-rise unit block.

That call took place at about 1.40am on Thursday and Vincent said police were on the scene by 1.41am, where they discovered a woman in the driveway of the unit block with critical injuries.

Witnesses said the man ran out to help the woman immediately after the fall and also reported hearing arguing before the woman fell. 

She was unable to be revived and died at the scene.

The woman, believed to be aged 39, is yet to be formally identified.

Police confirmed they had arrested a 40-year-old man they allege had been the woman’s partner.

He has since been released from custody and no charges have been laid.

Vincent said police had confirmed the man they spoke to on the phone was the same man they had arrested.

The residence the woman had fallen from was his, while she was believed to reside elsewhere.

Vincent said police had previous interactions with the pair, though he did not know if they were in a current relationship.

He said the man had an AVO in place for his protection, but pending identification of the 39-year-old woman, it could not be confirmed if the same AVO involved her.
