When two investigation officers (IOs) interviewed Han at around 3.15am, she was uncooperative and refused to provide her statement.
The police said she allegedly used vulgarities in Mandarin against one of the IOs.
Han recorded segments of her interaction with the officers, which went viral on social media after she posted the 11-minute-long video on Chinese social media platform Douyin on Oct 10.
It was shared multiple times on TikTok and Facebook.
The police added that on Oct 3, Han was allegedly drunk and was escorted by security officers at The Sail to her unit.
She allegedly pushed one of them on his shoulder, verbally abused him, and pulled his tie.
The police had said firm action will be taken against culprits who are abusive towards public servants and public service workers carrying out their duties.
If convicted of using abusive language against a public service worker or public servant, an offender can be jailed for up to a year, fined up to $5,000, or both.
Han is expected to plead guilty on Wednesday.
