The Central government was also not enacting strong laws to enable the CBI function like an independent body, she told reporters here.
"The CBI has turned into a caged parrot owing to growing interference of the Centre in its functioning. The Centre is also not enacting tough laws to protect the agency from pulls and pressures," Bedi said.
She welcomed the apex court's recent observation on the coal allocation scam probe, dubbing the CBI as "a caged parrot speaking in master's voice".
The apex court had asked the Centre to come out with a law before July 10 to insulate CBI from external influence.
"Some CBI Directors were also responsible for weakening the probe agency as they had acted on the directions of the government for getting lucrative posts after retirement or out of fear," she said.
