Prague  - The Czech police detained a 19-year-old German who allegedly raised his arm in a Nazi salute at a campsite near the city of Brno Friday, CTK news agency reported.

The man had been staying at the site during Brno's motorcycle races.

The police detained him on a lead from reporters, who noticed Thursday that he repeatedly made the salute while passing a tent fitted with a Nazi-era flag.

The suspect faces up to three years in prison for hate crime.

A Czech court will decide his case in accelerated proceedings within 72 hours, the report said. (dpa)
