Central Bureau of Investigation sleuths on Wednesday searched the residence of former high court judge Shamit Mukherjee for his alleged involvement in the Delhi Development Authority scam.

The CBI registered a case under the Prevention of Corruption Act and abuse of official position against the former judge as it found some important files in his residence, official sources said.

The sleuths also searched a dozen other places belonging to lawyers and some other people.

After seizing some documents from his residence, the former judge was taken to the CBI headquarters for questioning, the sources said, adding no decision had been taken yet to place him under arrest.

During raids on March 26, the CBI had found some important case files pertaining to Mukherjee's court from a guesthouse in Asiad Village.

It was believed that after the recovery of the files, CBI Director P C Sharma met Chief Justice of India V N Khare and apprised him.

Citing his wife's ill health, Mukherjee had resigned on March 31. Later, he tried to withdraw his resignation.

The DDA scam broke out on March 26 when the CBI registered a case against sacked DDA vice-chairman Subash Sharma, Commissioner (Lands) Anand Mohan Sharan, Commissioner (Planning) Vijay Rishbud and Director (Lands) Jagdish Chander.

Searches were carried out at their places and subsequently all were arrested.

The CBI also arrested some other persons, including the main conduit for Sharma, Dharambir Khattar, and manager of DLF Universal Limited Ajay Khanna.

The agency had allegedly found Rs 36 lakh at the residence of Sharan and Rs 4 lakh at the house of Rishbud.
