Tadic, whose house was also raided by the police on Friday, told reporters on Saturday that he did not think that charges had been pressed against him.
National Police Director Oliver Grbic yesterday confirmed that five persons had been arrested and that an investigation had shown that a group of people conspired to influence members of the Supreme Court, namely their verdict in the case of Glavas, a former member of the Croatian Parliament convicted of war crimes.
Grbic declined to give names of those arrestees. He said that between 12 and 15 people were either passively or actively involved in this scandal of trying to bribe judges.
The police have declined to give any further explanation.
The parliamentary deputy of the regional HDSSB party, Ivan Drmic, was also interviewed by police in Osijek on Friday in connection with the inquiry of who had attempted to influence Supreme Court judges before they handed down the guilty verdict against Glavas, who was eventually sentenced to eight years in prison.
Drmic said after the interview in the evening he had provided additional information to the formal complaint he had filed this summer in connection with this case.
Sanja Marketic, the local Glas Slavonije newspaper's deputy editor in chief, was also interviewed over this case yesterday. She went home last night after the police questioning.
