The diplomats barricaded themselves into a cabin on the train, refusing to allow a conductor inside to inspect tickets, or customs officials to inspect the cabin.
The men had diplomatic passports of the Democratic Republic of Korea, which are not valid for Finland.
The train conductor summoned the police onto the train. Kouvola police said that the two also resisted the police seeking to enter the cabin. The police had to use force to calm the situation.
The men were finally taken to the Kouvola police station to clear up the matter. After a few hours, the Finnish Ministry for Foreign Affairs granted the men temporary diplomatic immunity, even though their documents were inadequate.
The men, who were carrying diplomatic mail to Stockholm, were later escorted onto another train to Helsinki.
