The National Investigation Agency (NIA) on Friday arrested its former superintendent of police Arvind Digvijay Negi on the charge of leaking secret documents to an over-ground worker of the Lashkar-e-Toiba terror group.

An NIA spokesperson said Negi was arrested in connection with a case registered by the agency last November. The case pertains to the spread of a network of over-ground LeT workers for providing support in planning and executing terror activities in India.

“During the investigation the role of Arvind Digvijay Negi… was verified and his houses were searched. It was also found that official secret documents of the NIA were leaked by Negi to another accused person who is an over-ground worker of the LeT in the case,” the spokesperson said.
