An illegal immigrant has been arrested over the murder of an American nanny who had given him shelter at her Vienna apartment.
The 24-year-old Gambian had been wanted by police since the death of Lauren Mann, 25, from Grand Junction, Colorado last month.
He was arrested on Thursday in Bern, Switzerland, at an asylum center there after his mobile phone use was traced.
The location of the arrest suggests he was trying to use the immigration system to avoid being returned to his home country.
He was named by prosecutors in Austria only as Abdou I., under a legal convention that the surnames of alleged criminals are not released until they are convicted.
No mugshot was released by authorities in either country.
Austrian newspaper Krone also reported that he was already known to police, having raped an underage girl in Germany.
