BANGOR — A Canadian man has been arrested for allegedly exposing himself and masturbating publicly at Sand Beach in Acadia National Park.

Bodo T. Schmidt, 65, of Morrisburg, Ontario, faces a federal charge of indecent conduct.

Schmidt pleaded not guilty to the charge Wednesday. Bond was set at $1,000 cash.

The offense carries a maximum penalty of six months imprisonment and a fine of $10,000.

National Park Service rangers began investigating the allegations after several visitors reported three separate incidents on three parts of the beach around the same time Tuesday.

One of the alleged incidents took place within the view of young girls, according to an affidavit filed by Richard Rechholtz, a supervisory ranger. Another took place within view of a man’s daughter and her friend whose ages were not provided in the document released Wednesday.
