Manitoba First Nations Police Service officers are asking the public for help as they investigate shots fired at a staffed water treatment plant in a south-central community earlier this month. On Oct. 5, police were contacted by employees at the Sandy Bay First Nation water treatment plant who reported that the building had been shot at multiple times sometime in the previous 72 hours, the police service said in a news release on Monday. Police found numerous bullet holes throughout the building, which varied in size, including higher calibre rifles.
