Hailey Cheng Hei-lam, the Hong Kong student who raised concerns about the MediSafe app's development and patient privacy, has been arrested for alleged doxxing. Cheng is accused of disclosing personal data without consent with the intent to cause harm. The arrest occurred on Thursday, and Cheng reportedly admitted to posting doxxing content on her personal social media account. Cheng gained attention last year after questioning how a high school student could have developed such a complex AI-powered medical prescription app, MediSafe, which had won multiple awards. The app was reportedly commissioned by the student's father, a specialist doctor.
