Indian techie murder: New CCTV images released by Australian police

Australian police on Friday released a new CCTV footage hoping to find the killer of a 41-year-old Indian woman who was brutally stabbed to death in Sydney, just 300m from her home on March 7 this year while she was talking to her husband on the phone.

Sydney police is now looking to speak to a person who was seen in new CCTV footage walking nearby through Parramatta Golf Course near Jubilee Lane on the night of Prabha Arun Kumar's murder, Sky news reported.

"The person in the footage is the one person we have not been able to identify so far, after months of exhaustive inquiry," Acting Inspector Ritchie Sim said.

Sim said officers recently discovered the footage as they again canvassed the area around where the killing took place.

The investigations in one of the high profile case is expected to be widened to India with detectives from Strike Force Marcoala, formed by State Crime Command's Homicide Squad to investigate Kumar's death, due to travel to her home town in Mangalore, amid community plans to honour the slain woman with a service close to her birthday, the report said.

"Considering the nature of the investigation and because it is Prabha's home town, it is an obvious line of inquiry. It's important we don't speculate but we need to exhaust every line of inquiry," Sim said.

"Prahba's death has affected a lot of people, including her family in India. These people need closure and we are reliant on the publics' help to allow us to give them that," he added.

A plaque bearing Kumar's name will be unveiled during her birthday on November 22, the report said.

"We remain in close contact with Prabha's family and we have invited them to attend the memorial event. We will also assist in helping the family to make the trip to Sydney from India," Sim said.

Prabha was stabbed to death in Parramatta park in Westmead while she was on the phone with her husband in India.

Police had earlier released the CCTV footage of Prabha walking from the Parramatta train station just before she was fatally stabbed and had appealed to people for information to crack the baffling case.
