A second man was arrested yesterday over the kidnapping of Sau Akno, the son of General Sau Phan, deputy director of the general commissariat of the National Police, police said.

Sao Bon, 40, was charged with kidnapping Sau Akno on October 3 and faces up to 30 years in prison if convicted.

Sear Sambath, chief of the penal crime investigation office at national military police, said Sao Bon was arrested on Sunday in Kampong Trabaek district, Kandal province.

His arrest follows military police detaining and charging Suth Sophy in Sen Monorom district, Mondolkiri province, last week.

Other kidnappers, including suspected ringleader Nguon Soeur, remain at large.

Sear Sambath said six other suspected kidnappers had escaped to France, Sweden and Thailand, while some were probably still in the country.

Military police sent Sao Bon to Phnom Penh Municipal Court yesterday where he was charged and remanded in custody.

Sau Akno was kidnapped on October 3 in Chroy Changva commune, Russey Keo district.

The kidnappers released him on October 23 for an undisclosed figure suggested to be about $US500,000. Sau Phan and his family could not be reached for comment yesterday.

Sear Sambath said police are working with French police to search for the suspected kidnappers who remain on the run.
