Vukovic has the right to appeal the Rijeka court ruling.
Ahmetovic said in a brief statement that Vukovic was temporarily suspended pending the completion of criminal proceedings against him in Croatia.
According to Deputy Security Minister Mijo Kresic, it was Vukovic, the head of the Security Ministry's department for organised crime and terrorism, who had asked to be suspended as he would have more time to prepare his defence.
The Rijeka County Court on Tuesday sentenced Robert Dragin to six years and three months in prison for inciting to murder in the first degree, while Ivan Filipovic and Vukovic were sentenced to nine months each for supplying an explosive device that was to have been used in the attempted murder.
