Fond du Lac Police received a complaint Thursday just before midnight from a woman living at the Weathervane Apartments along East Division Street who was going through Halloween candy with her children.
The woman found what appeared to be pieces of a pill inside a package of Mike and Ike candy, which had a hole in the packaging.
The officer who responded describes a pill with a white interior and hard orange exterior. It looked like two pieces of a pill, but police currently do not know what it is.
The candy was received on Oct. 29 during regular Trick or Treat hours on Park Avenue, 13th Street or Ellis Street.
The investigation remains ongoing. Police are seeking to locate where the candy was given out and will try to determine if the pill is a narcotic or something else, possibly sending it to a crime lab for testing.
