Police sources said that Subhash Chandra, a senior executive with Jubilant Energy, who was arrested along with four other top officials of energy companies on Friday, was taken to Jain's office in the morning.
After searching Jain's office, the police team took him to the Noida office of Jubilant Energy. His office and some other rooms were searched by the police to recover stolen documents.
Asked about the issue, Delhi Police Commissioner B S Bassi said, "We have searched places which were necessary for the course of investigation. We may further raid places as our aim is to reach the bottom of the whole thing."
The five senior executives from top energy firms, who were arrested in the sensational corporate espionage scandal, will be produced in a local court here this afternoon and Delhi Police will seek their custody for further interrogation.
"We had arrested five persons. There interrogation is going on. They will be produced before a local court. We'll request court to send them to police custody, so we can further interrogate them," added Bassi.
The police chief also said that investigation is on in the case and it will end only when a charge sheet will be filed.
The five persons, who were arrested by the Crime Branch last night, have been identified as Shailesh Saxena from RIL, Vinay Kumar from Essar, KK Naik from Cairns, Subhash Chandra from Jubilant Energy and Rishi Anand from ADAG Reliance.
"We need to know since how long this has been going on and who all benefited from it," said a senior official.

Two energy consultants--Santanu Saikia, a former journalist, now running a petro web portal and Prayas Jain--were arrested on Friday morning while the five company executives were arrested in the evening.
