"The two suspects partly presented their defence and after the hearing I ordered that they be remanded in custody for 48 hours," investigating judge Vladimir Palinic told Hina late Friday night.
Palinic would not reveal any details of the hearing or of the charges that had been pressed by the police earlier in the day.
The judge confirmed that the suspects in question were Tomislav K. and Miroslav K., which the press had earlier learned from a source close to the police and the judiciary.
The source said that the two men were brothers who both had a criminal record.
The police said in a statement earlier on Friday that they had searched the suspects' apartment and found a large amount of equipment used for document forgery, Croatian ID cards, passports, driver's licences as well as a large amount of fire arms.
One of the men is suspected of forging a passport for General Gotovina on the urging of two Croatian nationals. The police would not reveal their identity. The pair were charged with incitement to forge a passport and aiding and abetting a Hague tribunal indictee.
According to media speculation, one of them is Marijan Pedisic, one of the lawyers representing the fugitive general.
In a brief interview with Croatian Television on Friday night, Pedisic denied any involvement in the passport forgery, saying that it was "absolutely not true" and that he had learned about the forged passport from the press. He said he had not been officially informed about the charges brought against him.
