Three persons, one from Gujarat and two from Uttar Pradesh, were arrested by the Karnataka Police for allegedly sharing sensitive information about the Indian Navy with handlers in Pakistan, The Indian Express reported on Sunday.

The Gujarat resident, 34-year-old Hirendra Kumar, was arrested on Saturday, The Indian Express reported. The two others, 29-year-old Rohit and 37-year-old Santri, both from Uttar Pradesh’s Sultanpur district, were arrested in November.

They have been booked under sections of the Bharatiya Nyaya Sanhita relating to acts endangering the sovereignty and integrity of India, as well as Section 3 and Section 5 of the Official Secrets Act, which deal with spying and the wrongful communication of official information, the newspaper reported.

Rohit and Santri were employed as insulators at Shushma Marine Private Limited, a subcontractor for the Udupi Cochin Shipyard.

The police alleged that Rohit collected confidential details about naval ships, including identification numbers, repair schedules and sensitive infrastructure information, and messaged them to Pakistani handlers, NDTV reported.

He continued to do so with Santri’s assistance even after being transferred from the site, The Indian Express quoted the police as saying.

Kumar allegedly provided Rohit with a SIM card registered in his name in exchange for money, the police alleged.

“The Gujarat-based accused was supplying SIM cards and OTPs that were used to activate WhatsApp accounts for communication with Pakistani handlers,” NDTV quoted Assistant Superintendent of Police of Karkala sub-division Harsha Priyamvada as saying.

The case came to light in November when the chief executive officer of Cochin Shipyard filed a complaint at Malpe police station about a security breach.

Meanwhile, in a separate case, five residents of Kashmir were arrested on Thursday by the Arunachal Pradesh Police on charges of spying, Inspector General of Police, Law and Order, Chukhu Apa told Scroll.

They have been booked under the Unlawful Activities Prevention Act and are accused of collecting “sensitive information from different parts of Arunachal Pradesh and sharing it with their Pakistani handlers”.
