The agency has now filed charge sheets without giving alleged role of these five state police officers.
It has filed two charge sheets recently before the Special CBI court here in the Nandigram firing in which 14 people were killed on March 14, 2007.
There was no reason forthcoming as to why the state government is still reticent on not giving the sanction, CBI sources said.
In one of the charge sheets, CBI named 132 private persons including some villagers but its request seeking sanction to prosecute two officers sub-inspectors Shambhu Das and Amit Hati and a Doctor, Laxmi Kant Ghosh, all state government officials, CBI sources said.
In another charge sheet, CBI has made 37 accused, all private persons, and sought sanction to prosecute Debashis Boral and Satyajit Bandopadhyay, both additional SPs, and Sekhar Roy, sub-inspector Nandigram, sources said.
The agency has also recommended disciplinary action against then Inspector General Arun Gupta, and then SP G Anil Srinivas, both IPS officers, to the state government.
