A huge swastika mowed into a field of grass is being investigated by police in Germany after it was spotted out of a plane window.

The 60-foot design – the symbol of Nazi Germany – was discovered carved into the earth near a residential neighbourhood in Brandenburg state.

Journalist Julian Ropcke discovered the giant swastika from a plane on 5th July.

He immediately posted footage on Twitter and tagged the Brandenburg Police saying: “Meanwhile somewhere in Brandenburg… [Is it] fully sewn up or still 86a, @PoliceBB?”

According to the German criminal code, section 86a bans the use of all Nazi symbols and iconography.

It prohibits the “use of symbols of unconstitutional organizations” outside the contexts of “art or science, research or teaching.”

Ropcke’s tweet prompted a rapid police response.

But when baffled officers came on site they found the notorious Nazi symbol had disappeared.

They still, however, began a criminal case against the owner of the field, whose identity was not disclosed by German media.

After the police action, Ropcke said: “Apparently, because of these tweets, there is now one 20-metre swastika less in the world.

“And the fact that it had already disappeared when the police arrived last night probably speaks against the thesis that someone just mowed badly here. Thanks, @PoliceBB!”

Disgusted Twitter users did not abstain from commenting on the journalist’s posts.

One of them, going by the moniker ‘CKlardek’, commented: “I thought Russians weren’t allowed into the EU at the moment…”

While another, called ‘Gallantree2018’, said: “What the… Unbelievable.”

And a уser called ‘civicnoonn’ said: “I hate modern Germany.”

Usage of swastika as a symbol of the Nazi Party has been banned since the end of the Second World War in 1945.

Exceptions are only allowed for swastikas used as religious symbols in Hindu, Buddhist, and Jain temples.

People who disobey the law and portray the symbol publicly face a jail sentence of up to three years.
