The CBI has quizzed officials of Haridwar municipal council in connection with discrepancies in two birth certificates issued to yoga guru Ramdev’s aide Balkrishna even as the civic body said an affidavit submitted by him on his parents’ citizenship has gone missing.

The CBI, which is probing complaints against Mr. Balkrishna for allegedly giving wrong information for getting passport, again visited Haridwar Municipal Council building last evening and interrogated executive officer Bhajan Lal Arya and other officials after searching the records of the office of birth-death registrar.

It was the second time in as many days that the CBI team visited the office after it came to light that two birth certificates were issued to Mr. Balkrishna. Police said that while in one of the certificates, the nationality of Mr. Balkrishna’s parents is mentioned as Indian, in the other it is Nepalese.

A CBI team, which reached Haridwar on Wednesday, had questioned Mr. Balkrishna.

When contacted, Mr. Arya said the CBI team searched for documents related to Mr. Balkrishna. “An affidavit (on his parents’ citizenship) submitted for getting birth certificate of Balkrishna in 1997 has been misplaced. We have taken one week’s time from CBI to give it to them. We have constituted a special team for its search,” he said.

Mr. Arya said the office of birth-death registrar has shifted several times and the documents of the year 1996-97 might have misplaced during the process.

A local intelligence unit Inspector Sanjay Bishnoi had said that the preliminary investigations conducted by the police revealed that Balkrishna has only one passport and it was renewed on Feb 7, 2007.

Haridwar Senior Superintendent of Police (SSP) Kewal Khurana has handed over all records related to the case to the CBI team, he had said.
