Greenpeace protester paraglides into Euros stadium, injures two men while landing

"The paraglider didn't want to go into the stadium yesterday," Mr Stephan said.

"The pilot wanted to fly over the stadium while maintaining the necessary safety distance and only let a balloon float into the stadium with a message to Volkswagen, a main sponsor, with the demand that they get out of the production of climate-damaging diesel and gasoline engines quicker," he said.

Mr Stephan said the pilot had no option but to make an emergency landing on the field after striking the steel cables attached to the stadium's roof.

"We are in the process of clarifying this and are working with everyone and of course we take responsibility and would like to emphasise again that we're very sorry, and that we apologise to the two people who were harmed," Mr Stephan said.

Munich police said they were investigating various potential violations of the criminal code and aviation act.

The police said none of the injuries were serious and the pilot himself — a 38-year-old man with an address in the south-western state of Baden Württemberg — was unharmed.
