Pressure is building on the Centre now to intervene in the custodial death case of Syed Haji Yousuf to ensure that there is a free, fair and expeditious probe. News X has found that a 2nd witness in the Srinagar custodial death case rocking the Omar Abdullah Govt has been muscled into silence. News X's Suhail Bukhari travelled to the National Conference leader's home in Ganderbal district and found that Yousuf Bhat has been barricaded behind the high walls of his house with a heavy security deployment. He's been made completely inaccessible to the media as well as the general public.
