The Central Bureau of Investigation (CBI) has arrested some more Gujarat police officials this week for the 'fake encounter' killing of Sohrabuddin Sheikh, his wife Kausarbi and friend Tulsi Prajapati. The manner in which the CBI has been closing in on top guns of the Gujarat government forms a pattern. This has also fueled speculation in the state that the investigative agency is all set to arrest Gujarat's minister of state for home Amit Shah on the charge of his complicity in the killings.

A certain degree of unease is palpable in the Gujarat government and the BJP circles over the CBI's conduct. This is why top BJP leaders rallied behind the Narendra Modi government and called the CBI the “Congress Bureau of Investigation”, which was working as a tool of the ruling party. While in Delhi LK Advani led a delegation to the president to register the party's concern over what he calls the “brazen misuse of the CBI” against the Gujarat government, in Ahmedabad chief minister Narendra Modi has been preparing for a full-blooded showdown with the centre should the CBI go ahead with its plan to tighten noose around the state home minister.
