Allegations first arose around early July and despite having police investigations returned, the it was resubmitted to the Attorney General Chambers for charges, resulting in Yong being charged in the Ipoh Sessions Court for rape of his househelper. It then emerged that there was ‘third party’ involvement and Ngeh Koo Ham publicly saying that he had met the person who was paid to make the police report along with the househelper. Despite an official request from the legal defense team to expedite the case and have it transferred to the high court for a faster hearing, the high court denied the transfer, requesting it be heard in the sessions court instead. The victim was kept under the witness protection act at the Indonesian Embassy of Kuala Lumpur, and despite pleas from the mother of the victim, was denied visitation rights while during case management, the defense had also appealed to the prosecution to withdraw the case, citing the chemist report that indicated no traces of his DNA was ever found in clothing items as well as in bodily fluids of the swab from the alleged victim

On 5 November 2019, Yong reported that his house was broken into while he was away on business, resulting in the loss of important documents as well as personal property. Oddly, the room in which his former househelper stayed in was left locked and untouched. The police confirmed that there was indeed a break in at Yong’s house, and while two safeboxes containing documents and valuables were taken, neither his high powered motorcycle, 60 inch TV nor other expensive items were taken

Yong opted to go on leave when pressure was stepped up calling for him to take leave-of-absence despite earlier rejecting the advise of the Menteri Besar Although he did proceed with the leave-of-absence, Yong returned to duty at the Perak State Legislative Assembly seating between November 16–22. It was then alleged that Perak DAP Chairman Nga Kor Ming was overheard in a recording chiding Yong for his initiative to return to work, further compounding the rumour that ‘black hands’ were behind the accusation. Allegations emerged during Yong’s appearance in court when a few hundred of his supporters emerged to call for the resignation of Nga.
