Four years ago, 10 terrorists entered the city by boat unnoticed and proceeded to lay siege to it by targeting key locations. While coastal security has been raised significantly since the incident, police have also approached a group of people more familiar with Mumbai’s coastline — its fishermen.

To keep a constant watch on the coast, fishermen have been provided around 50 phones for them to report any suspicious activity. There are around 70 to 80 associations of the Maharashtra Fisherman Society, among which 25 are active. They have been provided with two phones per committee, which are carried by fishermen going out at sea so they can collect details regarding security checks at sea.
