MP police had moved an application in Mumbai regarding this at the special court set up under MCOCA. The arrest took place on Friday at the JJ hospital where Pragya Thakur is going under treatment. It is still not clear when she will be brought to Dewas. A Dewas court has issued an order to present her before the court. Sunil Joshi was killed in Dewas in December 2007.
