A court in Haryana's Sonipat has summoned AAP supremo Arvind Kejriwal on February 17 on a complaint over his claim that the BJP-ruled state was mixing "poison in the Yamuna" river. The court issued the notice after a complaint was filed by an executive engineer of the Rai Water Services Division, Sonipat. Earlier, Haryana's Revenue and Disaster Management Minister Vipul Goel said the state government would file a case against Kejriwal for his remark.
