Murdered Melbourne girl, Sanaya Sahib was treated by paramedics at her home one week before her body was found in a creek.

The toddler's mother has links to Fiji.    

Habib Ali confirmed to the Herald Sun that his 15-month-old niece had to be treated after a seizure at his home in Heidelberg West on April 3rd.

Ambulance Victoria would not comment on why paramedics attended the home last week - which is the same address Sanaya's family had been visiting when she was reported missing on Saturday - but witnesses told the Herald Sun an ambulance was there for several hours.

Police continue to hunt for the man believed to have snatched Sanaya from her 22-year-old mother Sofina Nikat and fled.

Officers are searching through CCTV footage, with cameras in Olympic Park set to form a key part of the investigation.

Nikat told police she had pushed Sanaya in a pram along Perth Street, onto Liberty Parade, and into Olympic Park before the abduction.

She said a man passed her and then turned to push her to the ground from behind before grabbing Sanaya from the pram and running away through the park.

The alleged abductor has been described as dark skinned, six feet tall, and between 20 and 30 years old.

On Sunday night, forensic investigators and homicide detectives spent four hours combing Ali's home for clues.

An emotional vigil has been held for the toddler as the search for her killer enters a third day.

The Heidelberg United soccer club, which is based at Olympic Park, held a minute's silence before their match against Port Melbourne.

Sanaya's family members, including her grandmother, attended the match.

Police yesterday said a post mortem examination would be carried out on the toddler's body, but no details have been released.
