DNA extracted from bone pieces recovered in the Mehrauli forest area by the Delhi Police in connection with the grisly Shraddha Walkar murder case has matched with samples of her father, police sources said on Thursday.

The police had recovered 13 bone pieces from the area while searching for Walkar's body parts.

"The police has received the DNA report of the bones found. The DNA of the bones matches with the DNA samples of Walkar's father," a source said.

The bone samples were sent for DNA analysis to the Central Forensic Science Laboratory.

The report of Poonawala's polygraph test was submitted to the police by the forensic sciences lab on Wednesday.

Poonawala, 28, allegedly strangled his live-in partner Walkar and sawed her body into 35 pieces which he kept in a fridge for almost three weeks at his residence in South Delhi's Mehrauli locality. He later disposed of the body parts across the city over several days.
