German police arrested two Chinese tourists who made Hitler salutes outside the parliament in Berlin on August 5. The two middle-aged men, who were released on bail of €500 each, could face a fine or a prison sentence of up to three years.
Criminal proceedings have been started against them for using symbols from a banned organisation.
As reported by the BBC, Germany has strict laws on hate speech and symbols linked to Hitler and the Nazis.
A police spokeswoman told the Agence France-Presse (AFP) news agency that the men could leave the country during the investigation and that if a fine is handed down, the bail money they had already paid would probably cover it.
