Swedish Radio News in Malmö reports that Chief Prosecutor Mats Åhlund at the Swedish National Police-related Crimes Unit decided to interview the officers, the first to be officially questioned.
According to the prosecutor, the number of police officers questioned could shrink, depending on the results of the first initial questionings. The preliminary investigation is for suspected misconduct. Those found guilty of misconduct can be fined or imprisoned for up to two years.
Newspaper Dagens Nyheter first revealed that police were keeping the register of Roma people in September. Since then, the names of nearly 5,000 Roma men, women and children have been found on in the database.
Skåne police claim the list was kept to help fight crime, not profile an ethnic group.
The Swedish Commission on Security and Integrity Protection is expected to release its review of the registry on Friday afternoon.
