The Maharashtra ATS has recently filed a detailed chargesheet against Pradeep Kurulkar, a renowned scientist from the DRDO (Defense Research and Development Organization) posted as director of Research and Development Establishment (R&DE) Engineers (E). The chargesheet alleges that Kurulkar has been involved in sharing sensitive and classified information with a Pakistan Intelligence Operative (PIO) who identified herself as Zara Das Gupta to him. This information exchange is said to have taken place in exchange of explicit online conversations. The charge sheet also claims that Kurulkar downloaded some software which had malware and PIO may have got more sensitive details from his phone by accessing it with the help of the software.

The charge sheet, comprising 1,800 pages, was filed before the Pune sessions court last week. It highlights the gravity of the situation by revealing that the leaked information includes crucial details pertaining to various defense technologies. Some of the specific technologies mentioned in the charge sheet are the Brahmos and Agni 6 missile launchers, Surface-to-Air Missiles, Anti-Satellite Missiles, Rustom DRDO (an unmanned aerial vehicle), Mentor Missile, Rafael (presumably referring to the Rafael Advanced Defense Systems), AK system (possibly referring to AK-series firearms), Astra missile (an air-to-air missile), as well as defense drones. To address the legal process, Kurulkar’s lawyer was formally handed the charge sheet on Friday, ensuring that the accused scientist and his legal team are informed about the allegations made against him.

Two women’s statements

The ATS charge sheet which has 203 witnesses in the case including two women with whom Kurulkar was having an illicit affair. One of them was the vendor of DRDO’s Pune office which was headed by Kurulkar. The officials said that their statement was recorded to prove that he was having an affair with multiple women and hence he also fell for the honey trap and on the exchange of nude pictures sent by the Pakistani spy, shared very sensitive information despite knowing the fact that it can put the sovereignty and security of the nation at risk.

Officials have emphasized that the statements from the two women were recorded to establish that Kurulkar was engaged in multiple extramarital relationships. This fact is crucial to demonstrate how he became susceptible to a honey trap situation. The charge sheet presents these details to support the case against Kurulkar, highlighting the compromising situation he found himself in and the potential consequences of his actions on the nation’s security.

The charge sheet also includes highly sensitive information concerning defense projects, including their testing, designs, and related details, which were discovered on Kurulkar’s personal phone. “We cannot confirm whether this information was shared with the Pakistani spy, but it is against the official secret act for Kurulkar to possess such information on his personal cellphone,” stated an officer from the ATS.

Sensitive details

The information retrieved from Kurulkar’s personal phone consists of various sensitive details, such as the composition of materials used in defense projects, a PowerPoint presentation presented at a defense event in Gujarat, information regarding the Aakash Launcher, procurement details from the National Aerospace Laboratories, the VTOL Anonymous Aerial Vehicle system, and other similarly sensitive pieces of information. “Some data has already been retrieved by forensics, while some reports are still pending to ascertain if the same was shared with the Pakistan spy,” said an officer.

As per the charge sheet, the Pakistani spy, Zara Das Gupta, used to send links related to the projects Kurulkar was involved in, and he would then share detailed information about those projects. Gupta also used to share details and videos posted on DRDO’s official Twitter handle, providing explanations in great detail.

According to the charge sheet filed by the Maharashtra ATS, Kurulkar is alleged to have shared information about the CEO of a private company that supplies defense-related equipment to the Indian government. This company specializes in manufacturing defense robots, and Kurulkar claimed to have prior work experience with the CEO. Additionally, Kurulkar has shared details about several individuals associated with DRDO, but mid-day has chosen not to disclose these details due to their highly sensitive nature.

Furthermore, investigators have discovered that Kurulkar used to share DRDO duty charts with the Pakistani spy. “The chats revealed that Kurulkar shared his personal and official day-to-day work schedule, including meetings and locations, with a Pakistan Intelligence Operative (PIO),” states the charge sheet.

The comprehensive investigation conducted by the Pune Unit of the Maharashtra ATS suggests that the PIO may have gained access to Kurulkar’s entire phone. It is suspected that Kurulkar unknowingly downloaded software infected with malware, raising concerns that additional highly sensitive information might have been compromised and transferred to the PIO.

According to the charge sheet, Zara Dasgupta had sent some apps link such as and to accused Kurulkar’s mobile over WhatsApp and insisted he download and install it on his mobile. For that purpose she sent her 3 Gmail IDs and passwords to him. As per her direction, the accused downloaded the said apps on his mobile. By using this app there might be a chance of malware been inserted in the accused mobile and that such malware was also found by DRDO’s experts during his mobile forensics analysis, this detailed report has been submitted by DRDO to ATS. Also the said apps traces have been found in his mobile extraction.

The contact number used by Gupta was +47874137093. Moreover, the investigation revealed that Gupta utilized multiple Gmail IDs, namely,, and Notably, the IP address associated with these email accounts was traced to Islamabad, Pakistan, providing further evidence during the investigation. Kurulkar was arrested by Maharashtra ATS on June 3 based on the complaints made by DRDO under various sections of the Official Secrets Act.
