Hailey Cheng posts message on social media saying she has been arrested in connection with MediSafe saga, with source confirming news

The whistle-blower behind a suspected cheating scandal involving an award-winning medical prescription app developed by a student has been arrested for doxxing.
Hailey Cheng Hei-lam posted a short message on her social media accounts on Friday morning, saying she had been arrested in connection with the MediSafe saga. The posts included a photo showing a Notice to Arrested Persons with her birth name.
“Due to legal and procedural considerations, at this stage I will not be able to make any comments on the matter,” she wrote.
A source later confirmed the student, who entered the spotlight last year after raising concerns about the app’s development and patient privacy, was accused of disclosing personal data without consent to cause specified harm. She was apprehended on Thursday.
“Under caution, the arrested person admitted to using her personal social media account to post ‘doxxing’ content,” the source said.
The mobile app was reportedly developed by a Form Four student from St Paul’s Co-educational College in Mid-Levels and commissioned by the student’s father, specialist doctor Ronnie Poon Tung-ping.
