ISLAMABAD: Indian authorities have arrested a 21-year-old man named Alif Islam in connection with a major espionage case involving the unauthorised transmission of sensitive Indian Navy data to handlers believed to be in Pakistan.
The arrest of Alif Islam marks the latest development in an ongoing investigation that has exposed vulnerabilities in the supply chain of India’s strategic shipbuilding sector. Police officials describe the leaks as systematic and prolonged, potentially compromising national maritime security over an extended period.
The case originated in November 2025 when the CEO of Udupi Cochin Shipyard lodged a complaint at Malpe police station in Karnataka’s Udupi district. The complaint highlighted the illegal sharing of confidential information related to Indian Navy vessels under construction or repair at facilities linked to Cochin Shipyard Limited.
Investigators allege that the accused shared a confidential list containing identification numbers of naval ships, along with movement schedules, technical specifications and other classified details. These details were reportedly transmitted through popular social media platforms such as WhatsApp and Facebook to unauthorised contacts suspected of operating from Pakistan.
Alif Islam, a native of West Bengal who was residing in Marayur village in Kerala’s Idukki district, was apprehended on February 16 or 17, 2026, following a coordinated intelligence operation. Some reports indicate the arrest occurred in Munnar, Kerala, after tracking his movements.
Police sources have expressed suspicions that Alif Islam may be a Bangladeshi national using false credentials. Efforts are underway to verify his citizenship, background and possible foreign linkages through detailed interrogation and document checks.
This arrest brings the total number of suspects detained in the case to five. Earlier arrests include Rohit (29) and Santri (37), both from Sultanpur district in Uttar Pradesh, who were taken into custody shortly after the initial complaint in late 2025.
Another accused, Hirendra Kumar from Gujarat, was arrested in December 2025. The network appears to involve individuals from different states, suggesting a coordinated effort possibly motivated by financial incentives.
Authorities believe the espionage ring exploited subcontracting chains at the Malpe unit of Cochin Shipyard and related facilities in Kochi. Sensitive data from these shipbuilding sites, critical for India’s naval modernisation and maritime defence, was allegedly compromised for illegal monetary gains.
The accused face serious charges under multiple laws. These include Sections 3 and 5 of the Official Secrets Act, 1923, which penalise the unauthorised communication of information prejudicial to national security. Additional charges involve Section 18 of the Unlawful Activities (Prevention) Act and relevant provisions of the Bharatiya Nyaya Sanhita for acts endangering sovereignty and unlawful activities.
Investigators are examining digital evidence, including chat logs, transaction records and device forensics, to trace the full extent of the leaks and identify any remaining handlers or operators. One suspect and a possible Facebook page administrator reportedly remain at large.
The case has raised serious concerns about insider threats in defence-related industries. It underscores the risks posed by social media platforms in facilitating rapid and covert transmission of classified information across borders.
Defence analysts note that leaked details on ship identification, schedules and technical parameters could aid adversarial intelligence in tracking naval assets, planning disruptions or assessing India’s shipbuilding capabilities. Such breaches threaten operational secrecy and the safety of naval personnel.
The investigation has expanded beyond Karnataka, with probes reaching into Kerala, West Bengal, Uttar Pradesh and Gujarat. Coordinated efforts by state police, central intelligence agencies and cyber units continue to unravel the network.
This incident highlights ongoing challenges in securing sensitive defence information amid increasing digital connectivity. Authorities emphasise the need for stricter vetting of personnel in strategic projects and enhanced monitoring of communication channels.
As the probe deepens, officials have vowed stringent action against those involved in compromising national security. The case serves as a reminder of the persistent threats to India’s defence infrastructure from espionage activities linked to neighbouring countries.
