(CNN) -- Civil Police in Brazil say one of their helicopters made a startling discovery -- a huge swastika in the bottom of a swimming pool.

One of their helicopters was assisting in a kidnapping investigation this week when officers spotted the symbol on a property in Pomerode, Brazil in the southern state of Santa Catarina.

Local authorities say no charges would be filed, since the swastika is on private land and they say that the homeowner, who was not identified, is not promoting Nazism.

Police say the pool has had the swastika for 13 years.

Though the swastika is an ancient and sacred symbol for some cultures, its recent history has been associated with Adolf Hitler and the Nazi Party who adopted it in 1920.

The Santa Catarina region has a history of European immigration -- including Germans and Austrians -- and hosts a popular Oktoberfest in the city of Blumenau every year that "preserves the customs of their ancestors from Germany to form colonies in the South."

After World War Two, Nazi hunters tracked down Franz Stangl in Sao Paulo, Brazil. He was the commandant of the Sobibor and Treblinka extermination camps in Poland. He was arrested by Brazilian Police in in 1967 and died in a German prison in 1971.
