Ranchi, Aug 31 - With the Central Bureau of Investigation (CBI) conducting raids on the houses of one more Indian Administrative Service (IAS) official in Jharkhand Monday for alleged graft, senior bureaucrats say the crackdown on corruption is thanks to president's rule in the state.

Officials say the politician-bureaucrat nexus is so deep that no elected government has the will to take on the corrupt.

While the CBI Monday carried out raids at two houses of Pradeep Kumar, who was state health secretary till June, another IAS officer was suspended Aug 25 following CBI searches at his residences. Avinash Kumar was officer on special duty with former Jharkhand governor Syed Sibte Razi,

Both are secretary rank officials and charged with amassing assets worth crores of rupees. Senior IAS officers in the state say corrupt bureaucrats get away because the concerned ministers are often hand-in-glove with them.

'The IAS officials are involved in corruption as concerned department ministers overlook their corrupt practices. On many occasions the political bosses like to have a corrupt official as their secretary,' a secretary rank IAS official told IANS on condition of anonymity.

'Why was no action taken by any elected government? The raids at two IAS officers' houses were conducted as Jharkhand is under president's rule. Everybody in the bureaucratic and political circles knows about the officials involved in corrupt practices. The political bosses instead promote corrupt officials,' he added.

Another secretary ranked IAS official echoed the view. He said: 'A nexus of politicians, bureaucrats and contractors has formed in the state.
