The State Prosecutor's Office confirmed that the 49-year-old was arrested on its order by the State Investigation and Protection Agency.
Although he was sentenced by the State Court yesterday, he was let go pending appeal but was banned from leaving the country.
He was indicted and arrested in connection with the Srebrenica atrocity because when this eastern Bosnian town fell, he was the commander of a Bosnian Serb special police brigade which took part in mass executions and deportations of Bosniaks.
It is estimated that more than 40,000 Bosniaks were driven out of Srebrenica in July 1995 and that about 8,000 were killed.
Saric is charged with commanding the police units on the ground which carried out the ethnic cleansing together with the Bosnian Serb army.
The indictment contends that he personally ordered the capture of Bosniaks who were attempting to flee Srebrenica, the looting of those captured, and the murder of 15-20 prisoners in the village of Sandici.
Saric's policemen also took part in the murder of more than 1,000 captured Bosniaks in the village of Kravice, while those who survived were killed by police and soldiers, as well as in the murder of about 100 Bosniak men and boys captured while attempting to reach Tuzla, the indictment says.
The prosecution has proposed about 50 witnesses and enclosed hundreds of pieces of evidence.
The indictment needs to be confirmed by the State Court.
