Officials said the central government has ordered for the de-induction of 300 companies of these forces as it was difficult to keep them in the area owing to limited number of accommodation and other logistical facilities in the valley.
They were sent in only few weeks back.
While the bypoll in Srinagar was held on April 9, the one scheduled on April 12 in Anantnag has been postponed to May 25.
The officials added that these companies may be sent back to the valley again once again closer to the polling date in Anantnag.
The Kashmir valley has about 50 CRPF battalions for law and order and counter-insurgency operation duties.
