Police step up hunt for Mladic

Masked special police, backed by helicopters, searched a western Serbian town today as part of a stepped up hunt for UN war crimes fugitive Ratko Mladic, witnesses and media said.

The Beta news agency reported that police arrested two people in a three-hour search of the town of Valjevo, about 50 miles southwest of Belgrade, where the Bosnian Serb wartime commander is known to have lived in the past.
