New Delhi/IBNS: The Delhi Police have filed a 3000-page chargesheet in Sharaddha Walkar murder case citing testimonies from 100 witnesses and forensic evidence, media reports said.

Aaftab Ameen Poonawala allegedly strangled his live-in partner, then chopped her body into 35 pieces, stored them in his fridge and dumped them in Delhi's Mehrauli forest over 18 days.

The legal experts are examining the draft of the chargesheet prepared by the officials.

The 3,000-page draft chargesheet is expected to form the backbone of the final chargesheet, stated the reports.

It includes crucial forensic and electronic evidence along with 100 testimonies that the police have gathered over the course of a month-long investigation.

Investigators have added Aaftab's confessions, his narco test result and forensic test reports in the draft chargesheet, according to the reports.

Last month, a DNA test had confirmed that the bones that Aaftab Poonawala led the cops to in the urban forest were Shraddha's.

How the case came to light?

Aaftab Poonawala had got away with the murder for five to six months.

Every morning at 2 am, he would step out to dump the body parts, reports said.

The 28-year-old has been sent to five days in police custody after he was arrested from his flat.

He allegedly strangled his live-in partner Shraddha Walkar on May 18 after they had a fight.

He then chopped her body into 35 pieces and bought a 300-litre fridge to keep them, police said.

Over the next 18 days, he disposed of the pieces in different areas of the Mehrauli forest, they added. In fact, the accused bought a new fridge to store the body pieces.

During the questioning, Aaftab told the police that he and Shraddha had a rocky relationship and often indulged in fights.

He said that Shraddha had been pressuring him to get married and they would frequently quarrel about it.

Where did Shraddha meet Aaftab?

26-year-old Shraddha used to work at the call centre for a multinational company in Mumbai.

Aftab and Shraddha met on the dating app "Bumble" while both were working in Mumbai. The police may ask the dating app for details of his profile to find out whether he brought more women home while he had Shraddha's body parts in the apartment and whether any of them were a trigger for the murder.

The two started dating and moved in together. After her family did not approve of their relationship, the couple eloped to Delhi and started living in a flat in Mehrauli.

In September, Shraddha's friend informed her brother that her mobile phone had been switched off for over two months. This is when the family also checked her social media accounts and found no updates during this period.

In November, her father, Vikash Madan Walker, approached Mumbai police and lodged a missing person complaint.

During the initial investigation, the victim's last location was found in Delhi, and on the basis of this, the case was transferred to Delhi police.

Shraddha's father told the police about his daughter's relationship with Poonawala and suspected he is involved in her disappearance.

On November 8, Vikas Madaan Walkar came to Delhi to check on his daughter and found a lock on her flat. He approached the Mehrauli Police and filed a complaint alleging kidnapping.

In his complaint, Walkar alleged that Shraddha had earlier told him that Poonawala used to frequently beat her.

On the basis of this complaint, police arrested Poonawala on Saturday.
