A maths teacher isolated girls in their family homes so he could abuse them, a judge has heard.
Quy Huy Hoang is accused of sexually abusing four girls while tutoring them at his homes in south-west Sydney between May 2011 and July 2014.
With the help of a Vietnamese interpreter, the 76-year-old pleaded not guilty to four counts of sexual intercourse with a child under 10 and four counts of indecently assaulting a child under 16 in Sydney’s Downing Centre District Court on Thursday.
Hoang abused the trust three families had placed in him to raise their daughters, crown prosecutor Alex Morris said at the opening of the judge-alone trial.
Between May 2011 and March 2013, he allegedly sexually abused two sisters, one of whom was between three and five years old and the other between six and seven.
After experiencing multiple family tragedies, the girls’ mother received a call saying Hoang heard of their plight and wanted to help.
He tutored the sisters for free, initially teaching the girls in the dining room, but then convincing his mother that he would be more at ease in the toy room of their home.
“The reason Mr. Hoang suggested this was because he wanted the privacy of another room to have the opportunity to commit sexual offences,” Morris told Judge Penelope Hock.
Quy Huy Hoang is accused of sexually abusing four girls while tutoring them at his homes in south-west Sydney between May 2011 and July 2014.
The tutor is accused of taking cream from a black briefcase and using it to digitally penetrate one of the sisters.
On the same occasion, he kissed the girl on the lips and made her “pinky promise” not to tell her mother, Morris said.
The girl was separately forced to touch the tutor’s genitals, the court was told.
Her sister was assaulted when Hoang sexually touched her through her pajamas, the prosecutor said.
After the girls’ mother reported the matter to the police, the tutor was arrested at a Catholic church service in August 2014.
During a search of his home, police found a black briefcase filled with maths worksheets, as well as Vaseline, creams and lip balm.
One of the lip balm containers contained a substance chemically identical to KY Jelly personal lubricant, Morris said.
Hoang pleaded not guilty to four counts of sexual intercourse with a child under 10 and four counts of indecently assaulting a child under 16.
Police found several photographs of children on his mobile phone, including those of the four alleged victims.
Hoang is accused of sexually assaulting another girl and her school friend, both seven years old at the time, between March and July 2014.
He persuaded the mother of one of the girls to tutor them in her son’s bedroom, getting her to install a lock on the door and blackout curtains in the room.
Hoang allegedly forced a girl to touch his penis and digitally penetrated her.
He touched the other girl outside her pants and penetrated her with his fingers, causing her to burst into tears, Morris said.
“I don’t want to do it, I don’t want to be here,” the girl reportedly said when her mother asked her what was wrong.
The trial continues on Friday.
