Following the acquittal of all accused in the 2008 Malegaon bomb blast case, Vanchit Bahujan Aghadi (VBA) chief Prakash Yashwant Ambedkar has raised sharp and uncomfortable questions about the investigation and prosecution of the case. The special NIA court on Thursday acquitted all seven accused, including former BJP MP Pragya Singh Thakur and Lt Col Prasad Purohit both associated with Hindutva groups, due to lack of evidence.
