Congress chief Rahul Gandhi slammed Prime Minister Narendra Modi over the unprecedented feud in the CBI. A day after, the investigation agency filed an FIR against its no. 2 in a bribery case, Gandhi took to Twitter and said, ‘the PM’s blue-eyed boy, Gujarat cadre officer, of Godra SIT fame, infiltrated as No. 2 into the CBI, has now been caught taking bribes.’

The Congress president attacked Narendra Modi and said that, ‘Under this PM, the CBI is a weapon of political vendetta. An institution in terminal decline that’s at war with itself.’

The CBI has booked its second in command, Rakesh Asthana, on the allegations of receiving bribe from an accused probed by him in a case linked to meat exporter Moin Qureshi -- a charge levelled by the officer on CBI Director Alok Verma in his complaint to the Cabinet Secretary two months ago.

The CBI registered the case -- FIR RC 13(A) of 2018 -- against CBI Special Director Asthana on October 15 on the basis of a complaint from Satish Sana, facing probe in the 2017 case allegedly involving meat exporter Moin Qureshi, alleging the officer had allegedly helped him to get a clean chit.

The CBI claims to have analysed nine phone calls immediately after middleman Manoj Prasad was held in the alleged bribery case against its Special Director Rakesh Asthana to allege that there was panic after the middleman's brother got "wind" of the arrest, officials said Sunday.

The investigative agency has registered a case against Asthana on the basis of claims made by a businessman Sathish Sana, probed by him in a separate case, that he was asked to pay a bribe of Rs 5 crore by Manoj Prasad, an investment banker based in Dubai to get relief from repeated summons and a clean chit in the case, they said.

Surprisingly, Asthana who is second in command in the agency had intimated the Cabinet Secretary nearly two months back that Sana had allegedly paid a bribe of Rs 2 crore to Central Bureau of Investigation (CBI) Chief Alok Verma to get relief in the case.

The agency however claimed on Sunday that Sana had appeared before the Magistrate where he had stated that he made payments between December, 2017 and October, 2018 to a middleman who had cited his purported connection with Asthana to arrange relief for him.

On the basis of his claims, the agency arrested Manoj Prasad on October 16 when he was returning from Dubai to allegedly collect installment of the agreed bribe.

Nowhere in the statement which is now part of the FIR, made public nearly five days after registration, Sana had mentioned any direct meeting, interaction, or payment of bribe to Asthana.

According to the call data analysis done by the CBI, the phone calls were allegedly exchanged between Asthana and a senior officer of another intelligence who wanted to confirm the details, the middleman and the senior officer, wife of middleman with the senior officer and others, an officer claimed.

The sources claimed that call data records show that four calls were exchanged between Asthana and the senior officer on October 17, 2018, a day after the arrest.

They claimed that Somesh Prasad, brother of middleman Manoj Prasad, "somehow" got news of the latter's arrest on October 16, 2018 and immediately called his contact, the senior officer of the intelligence agency on the same day.

A call was then made by the officer to Somesh within a minute, they claimed.

Next day, the intelligence agency officer allegedly called Asthana to purportedly know the situation.

Three more calls were exchanged between the two, the agency claimed.

The officer of the intelligence agency also spoke to the wife of Somesh Prasad, they claimed.

In addition to the call exchanges, the agency is also depending heavily on the Whatsapp messages recovered from Manoj Prasad's phone, they claimed.
