"There are statements of police officers under CrPC 164 pointing fingers at them," the minister said.
Quoting from resignation letter of Vanzara, Sibal said, "Vanzara has said that 'being field officers, they have simply implemented the conscious policy of this government'."
"Clearly, all this could not have happened without Modi's knowledge," he alleged.
"All the pieces have now fallen into place. The highest authority in the state, from the evidence as disclosed, now needs to answer. Courts need to stand up for human rights and deal swiftly against those who, through fake encounters, eliminated people," Sibal said.
Responding to a query that whether the CBI which works under the Central government is protecting Modi and Shah from arrest, Sibal said, "CBI is not working under the Central government".
CBI, investigating the alleged fake encounter of Ishrat Jahan and three others, has not included any political leaders in chargesheets filed by it but has charged police and IB officers for murder and criminal conspiracy among other things.
