A woman whose family claimed she was raped and murdered by Pakistani hospital staff was not sexually abused and died of an allergic reaction, an autopsy report found.

Asmat Junejo's body was discovered by her distraught mother at the Sindh Government Hospital in Korangi on April 18.

The 22-year-old, from Ibrahim Hyderi, had visited the medical institute complaining of toothache.

Her family claimed there was evidence of sexual assault and murder but an autopsy has revealed anaphylaxis as the cause of death, according to local media reports.

Anaphylaxis, also known as anaphylactic shock, can kill within minutes and is a severe and potentially life-threatening reaction to a trigger, such as an allergy.

Deputy Inspector General for the East district Amir Farooqi said that the report also ruled out any sexual assault.

‘Further confirmation of this will be done through a DNA [test] whose report is still awaited,’ he said, referring to the DNA samples of three paramedics and two doctors that had been sent to a forensic lab in Jamshoro.

Family members were first told Ms Junejo had died due to a fatal antibiotic reaction but later claimed she was killed.

Ms Junejo's mother had been informed by the hospital that her condition was worsening - despite only going to the hospital complaining of toothache - and rushed to the facility.

But when there, she said she was told her daughter had been moved to the Jinnah Postgraduate Medical Centre.

This proved to be wrong and upon returning to the hospital, the mother said she started looking around the premises herself for her daughter.

The distraught parent discovered the victim's lifeless form lying on a stretcher in one of the back rooms, the young woman's aunt told local media.

The victim's family said she was a bright, independent and fiercely committed young woman.

Sindh Chief Minister Murad Ali Shah ordered a probe into the woman’s death.
