GUWAHATI, Oct 30: What has made Mangaldai MP Ramen Deka zip his lip on encroachment in Kalaigaon LAC by suspected Bangladeshis over the years? This is a plain question from Hindu Yuba-chattra Parishad: Assam to the BJP MP. Addressing the media at Atal Bihari Vajpayee Bhawan in Guwahati the other day, Ramen Deka alleged that 90 per cent of 9,000-bigha grazing reserves in Kalaigaon LAC has been under the illegal occupation of people of suspected tiolities. The MP even said that only around 60 of the 500 families residing in the area earlier are staying there now.
