The state government asked the Centre to recall 100 women paramilitary personnel deployed in restive Darjeeling and also replace SSB personnel with CRPF jawans.
A home ministry official said the "inappropriate" requests of the West Bengal government are being examined.
"A state government can't name the central force to be given. The reasons for recall of the women paramilitary personnel and SSB with CRPF were not immediately known," he said.
This is for the second time that the central government has sought a report from the state on Darjeeling.
The communication was sent after the West Bengal government told the home ministry to recall 100 women paramilitary personnel, belonging to the CRPF currently deployed in Darjeeling, and instead send men paramilitary personnel.
The West Bengal government also requested the home ministry to recall around 300 men SSB personnel and replace them with CRPF personnel.
