 For KBRF Radio.com News, I'm Dave Bishop. On Thursday afternoon, the Fergus Falls Park and Recreation staff reported to the Fergus Falls Police Department that a window of the lifeguard station at Pebble Lake Beach had been broken. The staff suspects the damage happened overnight and can be related to another incident on the 19th of June where fecal matter had been smeared on the same window and left at the lifeguard stand. Officials had a potential suspect, though they denied having any involvement. The incident remains under investigation.
