Story highlights A police helicopter spotted the swastika

Police say the pool has had the swastika for 13 years

No charges will be filed, according to police

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.
