Geneva: Prominent Austrian right-wing extremist Martin Sellner has been stopped by police while attempting to cross Germany’s southern border into Switzerland, media reported on Saturday. Sellner filmed the incident at the Constance-Kreuzlingen border crossing and posted the footage live online. The Swiss Federal Office of Police had imposed a temporary entry ban on Sellner on October 11 out of concern for public safety. The police in the Swiss region of Thurgau confirmed that a 35-year-old person had been stopped and held for further investigations. The person was "informed of the entry ban,” a spokesman said. They were then escorted to the border before leaving Switzerland again. The spokesman declined to say where that border crossing took place.(dpa)
