Robbers entered four buildings inside Clark Air Base during the past three days and stole about $92,000 worth of goods, the government-run Philippine News Agency reported Wednesday.

Thieves first broke into the American base's commissary and the civil engineering compound Sunday and took $33,000 in foodstuff and cigarettes, the agency said.

On Tuesday, robbers struck inside a training center and fled with aircraft testing equipment and spare parts estimated to cost $59,000, PNA said.

Clark police arrested two suspects Tuesday and turned them over to base authorities, the government news agency said. It didn't identify the suspects.
