An investigation has been opened into a banner depicting Prime Minister Recep Erdoğan with a Nazi symbol during the Turkish leader’s rally in Cologne 
on May 24, the Hurriyet Daily News reports.
Cologne police released a statement over the probe, saying “peaceful demonstrations” were held during Erdoğan’s rally at Lanxess Arena.
But a legal process against one person has been launched regarding the poster which carried Erdoğan’s photo along with a National Socialist symbol at the protest organized by the Federation of Alevi Communities in Germany (AABF), police stated.
Four people were also detained after attempting to block the way of Erdoğan’s official convoy at Ottoplatz.
Legal action has been taken against the four on charges of damaging property and injuring people during a protest held by far right Pro-NRW, the statement said.
