(STMW) — An active-duty soldier sexually assaulted a young female relative over a period of more than two years while staying at her family’s home in west suburban Oak Brook, according to prosecutors.

Army Specialist Andrew Hui, 36, of Oak Brook, was ordered held on a $750,000 bond Tuesday by Judge James Orel, after he was charged with one count of predatory criminal sexual assault and one count of aggravated criminal sexual abuse, according to the DuPage County state’s attorney’s office.

From April 2011 through June 2013, “Hui sexually assaulted his victim on multiple occasions while he was staying with the victim’s family at her home in Oak Brook,” a statement from prosecutors said.

The incidents “came to light when the victim alerted her father what Hui had allegedly done to her,” according to prosecutors. Her father called Oak Brook police, who contacted the DuPage County Children’s Center.

Hui was arrested without incident Tuesday afternoon and is next scheduled to appear in court June 22 before Judge Liam Brennan.

“What is particularly disturbing in this case is that the accused is not only a trusted family member, but he is also an Army Specialist and as such was looked up to by his victim,” state’s attorney Robert Berlin said in the statement. “He allegedly repaid that trust and admiration by sexually assaulting his victim in the most despicable manner imaginable.”
