In a major setback to CRPF in Naxal-hit Bijapur district in Chattisgarh, a constable turned his own service weapon - an AK-47 - at his colleagues.

The constable Sanant Kumar opened fire after getting into a scuffle with jawans from 168 Battalion in Basaguda. The incident took place around 5.15pm.

As the jawan sprayed bullets on five CRPF, four succumbed to fatal gunshot wounds while one personnel sustained critical bullet injury.   At least two of the fatally injured were Sub Inspector (SI) rank personnel.

CRPF evacuated the injured soldier by  MI-17 helicopter to Raipur. CRPF top official said Sanant Kumar was overpowered and finally handed over to Chhattisgarh police.
