NEW DELHI: Delhi Police on Friday said they have arrested officials of Reliance Industries Limited ( RIL ), Reliance Anil Dhirubhai Ambani Group ( ADAG ), Essar , Cairns and others in the corporate-espionage case that has rocked the capital.

The arrested people are Shailesh Saxena of RIL, Vinay Kumar of Essar, KK Naik of Cairns, Subhash Chandra of Jubilant Energy, Rishi Anand of Reliance ADAG.

The scandal got murkier on Friday as confidential documents including an input for the upcoming finance minister's Budget speech were allegedly leaked in the whole operation.

Oil minister Dharmendra Pradhan said he wants the guilty to be brought to book and would comment only after the investigation is complete. "Let the investigation be over. No one will be spared," he said.

Three diaries recovered from the accused, who have been arrested, have led to the revelation. According to sources, there could be many important names and numbers in these diaries.

The crime branch probe has indicated that the accused were in possession of papers from other ministries as well.

They will be interrogated to ascertain the identity of other people involved.
