Haridwar: Yoga guru Baba Ramdev's closest aide Acharya Balkrishna has failed to submit documents required by the Crime Bureau of Investigation (CBI) within the fixed time.

Confirming the reports, the CBI spokesperson said Balkrishna did not submit the original copy of the required documents.

According to sources, CBI is likely to take stern action against Balkrishna, as the top investigating agency is waiting for hearing in High Court on August 29 in this case.

CBI SP Nilabh Kishore said the agency had asked Balkrishna to submit the original copies of important papers in regards to the citizenship and passport case by August 27.

However, Balkrishna could submit only ration card, and failed to deposit the documents within the given time frame, the official added.
