During the 2006 FIFA World Cup in Germany, Horan was arrested by German police before he could stage a planned protest. He had written to German Chancellor, Angela Merkel, and "The Kingdom" newspaper in County Kerry, Ireland, informing them that he planned to dance a peace jig outside the stadium in Berlin before the World Cup final. He told "The Kingdom" he would carry posters declaring "Adolf Hitler was a good leader who was following the word of Christ", give the Nazi salute and light a candle for Hitler at the Gestapo headquarters. He spent two months in custody awaiting trial but was released on 15 September 2006 when the judge discharged the case.
