 On Thursday afternoon, the Fergus Falls Parks and Recreation staff reported to the Fergus Falls Police Department that the window of the lifeguard station at Pebble Lake Beach had been broken. The staff suspects the damage happened overnight and could 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 have denied having any involvement. The incident is under investigation.
