"We have been tracking Subramani, the maker of illegal guns for quite some time and we have arrested him after a raid," Police Superintendent, Villupuram, V Vikraman told PTI.
Four single barrels guns that were being assembled were seized besides many implements, equipment and raw materials used for manufacture of guns.
"The factory was located in a remote, inaccessible location which is about 25 kilometres inside the jungle in the ambit of Pappathimoolai hamlet," he said.
Based on the information provided by the 50-year-old Subramani, ten others who were in possession of similar guns were also arrested.
Investigation revealed that he has been selling guns for Rs.10,000 to Rs.15,000 to villagers in the hills.
"Subramani and others claim that the guns were used only for hunting," the district police official said.
