Another interlocutory petition was filed last month against another former chief minister and Lok Sabha MP Arjun Munda. He has been charged of amassing wealth more than his known sources of income.

Moreover, an interlocutory petition has been filed against central Food Processing Minister Subodh Kant Sahay. He has been accused of floating three companies in his brother's name.

The hearing of Durga Oraon's petition is underway in the Jharkhand High Court. The court has sought details of the tax filed by Madhu Koda and five other ministers from the Income Tax department.

A First Information Report (FIR) has been lodged against Koda and three former ministers including Bandhu Tirkey, Kamlesh Singh and Bhanu Pratap Sahi.

The vigilance court has also issued arrest warrants against two former ministers -- Enos Ekka and Harinarayan Rai.
