Police stopped the man in a shopping centre in Karlstad, western Sweden on Friday afternoon. They confiscated the t-shirt and filed a report. The crime is being classified as incitement to ethnic hatred, local newspaper Nya Wermlands-Tidningen reports.
Swedish incitement laws (hets mot folkgrupp) criminalise statements that threaten or offend individuals on the grounds of race, skin colour, nationality, ethnicity, faith or sexual orientation. The crime is punishable by up to two years in prison or fines.
