Maybe a got to them?
Around midnight, Minneapolis Police officers on "routine patrol" around the northern edge of Lake Harriet spotted a man and a woman swimming, according to the police report of the incident. As swimming is not allowed in the lake at that time of night, according to Park Board rules, officers came down to the beach and called the pair in to land.
"On returning to the beach, officers observed that both were completely nude and not wearing any clothing," the report noted.
After the man and the woman were dressed, officers identified them via their drivers' licenses and later mailed citations for indecent exposure to the Kingfield residents' houses.
