Philippine police say they've rescued a 4-year-old American boy who was held for ransom for eight days and that five suspects have been arrested.

Isagani Nerez, head of the police anti-crime unit, said Friday that the boy was seized by three gunmen Dec. 6 in the Philippine capital while traveling in a car with his Filipino mother. A ransom was paid three days later but the kidnappers demanded more money before releasing the boy.

Nerez said police feared the boy would be harmed and traced his location with the help of FBI agents to the kidnappers' hideout in Prieto Diaz town in eastern Sorsogon province. On Wednesday, police stormed the site and rescued the boy unharmed.

Nerez said the boy was in good health and reunited with his family.
