There are several ways to link Sri Lankan Eastern coast with Tamilnadu. One is the direct sea link. We know that Tamilnadu poachers regularly visit the Sri Lankan eastern seaboard up to Mulativu area. It is no difficult to smuggle contraband that way. Another way is trough Mannar. Mannar has sizable Muslim population plus there were illegal land grabbing done by Muslims under the auspicious of a power Muslim minister in the government right near the Mannar town few years back. These new Muslim only towns could be used as smuggle points. In fact these strategic placement might have done to facilitate the smuggling operations.
