Defending his law minister Somnath Bharti, Arvind Kejriwal today called the court observation "completely wrong."

"A sting operation has been called tampering of evidence - it is not tampering of evidence," said the Chief Minister.

Bharti was indicted for tampering with evidence by a court in Patiala.

According to a report in a leading national daily, a special judge of the Central Bureau of Investigation had indicted Bharti and his client Pawan Kumar after the agency accused them of trying to influence a prosecution witness.

Bharti had allegedly spoken to the prosecution witness and discussed the case.
