"Do you think CBI is full of bunch of fools who will risk their entire career by making false allegations, non-existing allegations which are going to be examined by the Supreme Court?" Congress spokesman Abhishek Singhvi told reporters here countering the opposition charges.
On former Gujarat Minister Amit Shah's claim that he was being arrested under false allegations by the CBI, he said the BJP leader was trying to "fool the country" by making such remarks.
"Chargesheet is not made overnight. Chargesheet is a collection of evidence... Here, in over five-six months of investigation the CBI has got enough evidence against Amit Shah," Singhvi said.
He claimed there have been attempts to delay the course of law and said, "The law will take its own course. There have been attempts to delay that course and obstruct it."
Another Congress spokesman Shakeel Ahmed said after Shah, it was the turn of Chief Minister Narendra Modi to face some "uncomfortable" questions in the case.
He claimed the BJP was "nervous" with the developments in the Supreme Court-monitored probe in the case and was using pressure tactics to block the probe.
"Shah was only a Minister of State for Home.The transfers of many IPS officers in the state were made by Narendra Modi. It is our understanding that these uncomfortable questions will be asked... Modi will have to answer them," Ahmed said.
"BJP is nervous and afraid that the investigation may go beyond Amit Shah and, hence, are using pressure tactics to block further investigation into the case," Ahmed claimed.
The CBI today arrested Shah in the sensational case when he appeared before the agency for questioning in Ahmedabad after evading CBI officers for three days.
Ahmed said law will take its own course in the matter and added "it is unfortunate that the BJP was trying to defend a cold blooded murder (of Sohrabuddin)."
The Congress spokesman said the Shah had no option but to appear before the CBI as there was no possibility of any court granting him anticipatory bail in the case.
