Kochi: The National Investigation Agency (NIA) conducted extensive raids at the Cochin Shipyard Ltd on Wednesday concerning the leaking of sensitive information regarding defence ships. Two contract workers of the CSL were also arrested in the case, sources said.
However, the identity of those arrested has not been revealed. Some media reports said the national anti-terror agency apprehended an Ernakulam native and a Thiruvananthapuram native.

The NIA team from Hyderabad inspected the shipyard, employees' quarters, and other locations. The raids were prompted by suspicion of espionage. The NIA team probing the 2021 Visakhapatnam espionage case took the two workers into custody. 

The case involves the leakage of classified defence information through a Pakistan ISI spying network.
