Union Home Minister Amit Shah on Thursday said that the Centre wants those who entered India illegally through infiltration (referring to Bangladeshi immigrants) to return to the places from where they came.Speaking at a function in Gandhinagar, Shah said if they (illegal immigrants) return voluntarily, the West Bengal Government will neither file cases against them nor hinder their return, and will instead assist them in going back. He expressed hope that infiltrators would return on their own even before the identification campaign begins.The Home Minister reminded the audience that during the recently concluded West Bengal Assembly elections, the BJP had promised that once their government was formed in the state, the work of fencing the border would begin immediately.He said that West Bengal Chief Minister Suvendu Adhikari has handed over 600 hectares of land to the Border Security Force (BSF) within seven days of the formation of the government, for completing the fencing work along Bangladesh border, even though the deadline it had promised was of 45 days. He added that 121 hectares of land for the Chicken’s Neck Corridor had also been handed over to the Centre.Shah said that fencing and building anti-infiltration infrastructure along the border was a priority of the Central Government. He claimed that during the rule of the previous government in West Bengal, infiltration used to take place every day, but now infiltrators have started returning on their own.He said that the West Bengal Government had established detention centres and the government wanted those who entered India illegally through infiltration to return to the places from where they came.
