A father from Hahake district, Tongatapu has faced court accused of drugging his own daughter with crystal meth, also known as ice before raping her while his wife from a second marriage was watching.

The father, who cannot be named to protect his daughter’s identity, has pleaded not guilty to 15 charges including incest with daughter, procuring sexual acts by administering a drug and rapes, Kakalu ‘O Tonga newspaper has reported.

He pleaded guilty to one count of domestic violence after he attacked and threatened her daughter with a pair of scissors.

The Supreme Court heard the girl, whose parents were separated, and her mother was living in New Zealand at the time, had been staying with her father in Hahake from September 2016 to January 2017.

The man committed the offences over two months between December 2016 and January 2017.

The abuse apparently began when the girl was with her father in their house while his wife and their young children went to a funeral.

The girl was about to go to a friend’s house when her father allegedly forced her to take the drug.

She took it after her father threatened her. She said she felt weak and tired after taking the drug before her father allegedly raped her, the paper reported.

Since then whenever his father returned home drunk he entered her room and raped her, the girl claimed.

She alleged she was sometimes raped by her father while her step-mother was watching.

The case was reported to Police after the girl opened up to a maternal aunt and told her about her ordeal, and the aunt contacted the police.

It is understood the trial before Justice Charles Cato was set to continue next week.
