The Danish government has remained tight-lipped after allegations that the Turkish government may have plotted the assassination of political opponents living in Denmark.

The alleged plot against supporters of Turkish cleric Fethullah Gülen, who has been accused of being behind the failed coup attempt in summer of 2016 by Recep Tayyip Erdogan’s government, was discovered by broadcasters Sveriges Radio and Denmark Radio in June.

Shortly after the broadcasters informed the Danish security police about the potential targets for assassination, those involved were taken into police protection.

The plot is not the first against a Turkish national living in Denmark, according to Sveriges Radio, who said that they were contacted by a man who they call Mehmet, who told them police visited his home in January.

“They said they had been advised that I should be assassinated during the week and that they had to go to a sheltered place,” he said.

The criminal biker gang Osmanen Germania, who are alleged to have ties to the government of Turkish President Recep Tayyip Erdogan, are believed to be the ones that would have carried out the targetted assassination.

Osmanen Germania was recently banned by the German government in July following raids on the organisation’s clubs in four regions of the country. Interior Minister Horst Seehofer justified the ban by claiming members of the group had committed serious crimes.

The group is also known in Germany for harassing Kurds and political opponents of President Erdogan, with German broadcaster Bayerischer Rundfunk claiming the group also has ties to the ultra-nationalist Grey Wolves who have clashed with Kurds openly in the past.

At the Danish parliament Friday, a closed-door meeting was held about the issue. Danish politician Nikolaj Vilumsen, a member of the far-left Red-Green Alliance, slammed the fact that neither Foreign Minister Anders Samuelsen nor Justice Minister Søren Pape Poulsen would answer any questions on the subject and how the government has dealt with it on a diplomatic level.

The incident echoes a similar plot that was uncovered in Germany in December of 2016, in which a Turkish spy was caught allegedly plotting to kill several Erdogan opponents in Germany and Belgium.

31-year-old Mehmet Fatih Sayan was arrested by Hamburg police and was also thought to have been spying on Kurds in Germany for the Turkish National Intelligence Service.
