Delhi Chief Minister Arvind Kejriwal today lauded the Delhi Police for cracking the petroleum ministry document leak case and advised it to trace out those who had benefited from leaked information.
"Compliments Delhi police for bursting espionage racket. During interrogations, police should try to reach top people, who would benefit from leaked information," Mr Kejriwal tweeted.
With seven arrests on Friday, the total number of those held has risen to 12.
On Thursday, police had arrested five people - two petroleum ministry employees and three others - for stealing documents and leaking them to corporate houses.
The police complaint said the stolen documents included inputs for the forthcoming union budget and a letter concerning the prime minister's office. The documents were also related to the power and coal ministries, police said.
The first information report (FIR) details how the "secret papers" were photocopied after office hours by the arrested, who used duplicate keys to open the offices after entering Shastri Bhawan with the help of forged identity cards and temporary passes obtained fraudulently.
