The 18-year-old faces four charges - one count each for using abusive words on public servants, obstructing a policeman from carrying out his duties, voluntarily causing hurt to a police officer and mischief.
At around 3.15pm on June 6, 2013, she allegedly prevented Staff Sergeant Chris Tan Zhi Yong from putting Chng, her older brother, in handcuffs by pulling the policeman's lower arm.
About 1½ hours later, she allegedly used vulgar language on three other police officers - Cpl Tan, Sgt Sritharchana R. Jayaprakas and Assistant Superintendent Deng Qiyuan.
She is also accused of kicking Sgt Sritharchana on her knees and stomach at around 5pm that day, causing bruises on both knees and tenderness around the officer's right lower ribs.
At 5.15pm, she allegedly kicked the rear right passenger window of a police car, causing the internal cover of the door to crack. According to court papers, the damage amounted to $100.
Her case is still pending.
