The Maharashtra cyber police on Tuesday detained a 35-year-old man in Rajasthan for his alleged involvement in the Reliance Jio customer data leak that was reported on Sunday. The suspect, identified by his nickname “Imran Cimpa”, was arrested in Churu district, Rajasthan, and is said to be a college dropout, PTI reported.

“Further evidence collection and interrogation is in process,” Balsingh Rajput, superintendent of Maharashtra Police’s cyber department, told PTI.

After the cyber police zeroed in on the location from where the breach had happened, they contacted the Churu police. The suspect was detained 24 hours after the investigation began.

The accused’s computer, mobile and storage devices were seized and he will be brought to Mumbai later on transit remand, Inspector General of Police Brijesh Singh, Maharashtra cyber police, said. Currently, a team of Navi Mumbai police and Maharashtra cyber police, along with officials from Reliance Jio, are conducting searches in Rajasthan.

The customer data, including phone numbers, email address and/or Aadhaar details, were leaked on a website. However, the URL was later blocked.

The mobile network has more than 120 million users in India, potentially making this the biggest data breach ever in India. However, Reliance Jio had said that its customer data is safe.
