Cadres of CPN-Maoist led by Netra Bikram Chand have been arrested by police while they were trying to erect a black flag at the residence of Investment Board's Chief Executive Officer Radhesh Panta. Former state minister Padam Rai and Ishwari Dahal were among the 17 arrested while the group had gone to erect the black flag alleging Panta of being a corrupt and a water resource mafia. Saying the agreement to hand over the Upper- Karnali Hydropower Project to Indian company GMR was against the country's interest, the Chand- led Maoist party has been putting the blame on Panta for the agreement.
