KUALA LUMPUR, Malaysia (AP) — A Malaysian security official says a Chinese national working at a fish farm in eastern Malaysia has been kidnapped by gunmen, sparking fresh concerns of security threats on Borneo island.

The incident comes a month after suspected Filipino insurgents seized a Chinese tourist and a hotel worker from a dive resort in eastern Sabah state.

The official, who declined to be named as he isn’t authorized to speak to the media, says the man was abducted by five gunmen clad in army fatigues. A Philippines official, who also requested anonymity as he isn’t authorized to give details, said the kidnappers were believed to have taken the man to the southern Philippines by boat.

China’s Xinhua News Agency says Beijing has urged Malaysia to speed up efforts to rescue the man.
