Bosnian police have arrested four men, including an active officer of the state intelligence agency, suspected of committing war crimes during the country's 1992-95 conflict.

A statement from the prosecution office said Tuesday the men were senior members of the Bosnian Serb police during the war and that they are suspected of illegally imprisoning, beating and torturing Muslim Bosniak civilians in the northeast city of Janja.

The statement says the torture resulted in the death of three civilians while many others suffered lasting physical and psychological damage.

The suspects were arrested in the northeastern town of Bijeljina.

More than 100,000 people died in the conflict.
