Sources said the closure report into the preliminary enquiry (PE) has been submitted to the Supreme Court. But there was no official confirmation whether Singh was examined in the case, while he was summoned as accused in the Talabira coal block allocation case.
They said the agency could not gather enough prima facie material to convert the inquiry into an FIR, resulting in its closure.
"As per directions of the Supreme Court of India, CBI is not in a position to share any information relating to inquiry investigations in coal cases," CBI spokesperson said.
The sources said PE was registered on the allegations that while applications were invited for West of Radhikapur but a promotional Ramachandi block was added to it later. The Ramachandi block was allocated to JSPL. The block lies close to another coal block which was already allocated to JSPL.
The Ramchandi block, which has estimated 1.5 billion tonnes of coal reserves, was allocated for ambitious coal-to-liquid project in February, 2009.
The block was deallocated by the UPA Government on February 17, 2014 on the grounds that the company failed to develop it.
