The Criminal Court on Monday sentenced a 30-year-old woman who forced her daughter into prostitution to a long term in prison.
The woman was identified only by her first name, Lucksana, 30, from Phetchabun province.
The woman was convicted of forcing her daughter, then aged 12, into the sex trade between June and September last year by leaving her with a massage parlour owner in Tokyo.
The woman was sentenced to seven years and six months in prison.
The girl sought help from the Tokyo Regional Immigration Services Bureau in mid-September and she is now under the care of the Pavena Hongsakun Foundation.
Her mother left Japan to Taiwan in September last year and was arrested in New Taipei City in November for overstaying, and extradited to Thailand in December.
The court said the woman had previously worked overseas as a masseuse.
