Home minister Rajnath Singh on Saturday alleged that the theft of classified documents from government ministries had been happening "for a long time" but no guilty person will be spared.
"Jaldhi doodh ka doodh, paani ka paani ho jayega (everything will be clear). No guilty person would be spared and strictest punishment would be given to them," he told reporters in Delhi when asked about the arrest of government clerks and corporate executives about the theft of documents from the ministry of petroleum and natural gas.
Singh did not rule out that middlemen and government officials were in cahoots and more ministries could be investigated. "It is possible. I am not ruling out any possibility. Delhi Police is investigating the whole issue. I think the issue will come to light very soon," he said.
"But it is certain that such things have been going on for a long time and that is why the situation has reached such a stage. If we were not alert, these things would not have come to light," he said.
The Delhi Police will on Saturday produce five executives, who work for energy firms and were arrested on Friday for alleged corporate espionage, before a court and seek their custody for interrogation.
Shailesh Saxena of Reliance Industries Ltd, Vinay Kumar of Essar, KK Naik of Cairns, Subhash Chandra of Jubilant Energy and Rishi Anand of ADAG Reliance. They have been booked under laws relating to criminal conspiracy and dishonestly receiving stolen property.
The Delhi Police have so far arrested 12 people who they believe were involved in the scam to sell secret government documents to private energy companies including the petroleum and natural gas ministry.
Kejriwal asks cops to reach top people
Delhi chief minister Arvind Kejriwal, on his part, said Delhi Police should now target the "top people" benefiting from the leak.
"Compliments (to the) Delhi Police for busting espionage racket. During interrogation, police should try to reach top
people, who would benefit from leaked info," he tweeted.
The ruling Aam Aadmi Party (AAP) on Friday had demanded setting up of a commission to probe the matter in a time-bound manner.
The party has often been at loggerheads with the Delhi Police. In his earlier stint as a CM, Kejriwal had staged a dharna outside Rail Bhavan demanding action against police officials in three different cases, of which one was related to a rape of a foreign national.
