The nation's top court on Friday confirmed a 10-year prison term for a 44-year-old man for raping his own teenage daughter and coercing her to provide false testimony.

The father, only identified as his surname Kim, was found guilty of raping and brutally assaulting his underage daughter on multiple occasions in 2012 in his house.

The Supreme Court also found Kim guilty of fabricating a key piece of evidence during the course of the trials by forcing the daughter to recant earlier testimony. Kim ordered his daughter to say that she had lied about rape charges in exchange for giving up parental rights after his release from prison.

"The court agrees with earlier rulings, considering the defendant's relations with the victim and various circumstances," the Supreme Court said in its ruling. "The defendant committed a heinous crime against humanity, inflicting unbearable suffering on his daughter," the court added.

The court also upheld the lower courts' order that Kim wear an electronic monitoring anklet for 20 years after serving the jail term and that he go through 160 hours in a rehabilitation program.

Amid constant calls in Korean society for tougher punishment for those who commit brutal sex crimes against youths, the parliament revised a law last month to increase the penalty for sex offenses against minors.

Under the revision, sex offenders found guilty of raping minors can receive a maximum sentence of life in prison. (Yonhap News)
