New Delhi, Nov 19: The CBI is ascertaining the authenticity of the video tape allegedly showing Dilip Singh Judeo accepting money, the identity of the bribe giver, whether it was a sting operation or a "credible happening", the agency Director P C Sharma said today. "The investigations have started. We have asked the Indian Express for the video cassette," he told a news agency.

Asked whether a CBI team would be sent to Chhattisgarh to question Judeo, Sharma said "let us first get the tape and after examining it, we will decide whom to talks to". On whether the tape could have been 'doctored', the CBI chief, who lays down office after joining IPS in 1966 and serving the agency for 20 years, said "everything is possible" with modern digital technology.

"We have to find out whether it was a credible happening or a sting operation and whether something had been contrived. All these things are necessary (for the probe)", he said. Bureau Report
