Tonga police have revealed details of the kidnapping of two Chinese men, a father and son, in Nuku'alofa two weeks ago.
They say a ransom of 216 thousand US dollars was demanded and paid by relatives of the victims, who were then released.
Deputy commissioner, Unga Fa'aoa says the men were unharmed.
He says about 80 percent of the money had been paid by cheque and this has been recovered but the balance, in cash, is still missing.
The commissioner says five men, who include 3 Chinese, have been arrested and charged with armed robbery and unlawful imprisonment.
They have been remanded in custody for a month.
Commissioner Fa'aoa has reminded people that armed robbery is an offence punishable by 20 years' imprisonment.
