The 34-year-old man pleaded not guilty to both charges before judge Nik Habri Muhamad.

He was charged with committing non-physical assault by causing his 17-year-old sister to watch or hear persons engaged in sexual activity.

The offence, under Section 16(d) of the Sexual Offences Against Children Act, was allegedly committed in a house here at 10pm on April 6.

He faces imprisonment of up to 10 years, or a maximum fine of RM20,000, or both, if found guilty.

He was also charged with committing physical sexual assault on the girl at the same location at about 11am on April 8.

The charge, framed under Section 14(a) of the same law, provides imprisonment of up to 20 years and is liable to whipping upon conviction.

The man was not allowed bail and the court set May 6 for mention.

Deputy public prosecutor Siti Edabayu Subhan prosecuted, while the accused was unrepresented.
