Olivia Tsao Stalker Case: Singaporean Woman Jailed, Set for Deportation

A Singaporean woman has been sentenced to six months behind bars in Taiwan for persistently stalking and harassing Mandopop singer Olivia Tsao — a case that’s raised eyebrows across both countries.

On 5 June 2025, the New Taipei District Court found Cassandra Low, believed to be in her 30s, guilty of endangering Tsao’s personal safety, following her across the city, and repeatedly sending threatening and insulting messages. 

She’ll serve six months in jail, or pay a daily fine of NT$1,000 (around S$43) instead — and will be deported after completing her sentence or paying up.

Low, reportedly a long-time fan of the 38-year-old Golden Melody Award-winning singer, had begun messaging her in late 2023 via Instagram, Facebook, and email. But when Olivia cut off contact and blocked her on socials, things took a nasty turn.

Low allegedly lashed out online, posting insults and threats directed not just at Olivia Tsao, but also at her family and manager. At one point, she even made disturbing claims about harming people close to the singer. The situation got so tense that both Olivia and her manager had to move house for their safety.

Then in February 2025, things escalated offline. Low flew to Taiwan, tracked Olivia down to Banqiao High Speed Rail Station in Taipei, and physically blocked her at the ticket gate.

According to the court report, Cassandra Low grabbed Olivia’s suitcase, tugged at her phone accessory, and stopped her from calling for help — demanding the singer unblock her on social media.

The incident was caught on camera and reported to police. Investigations found that Low had created multiple fake accounts to keep tabs on the singer after being blocked repeatedly.

According to Olivia Tsao’s manager, the fan had previously spoken to the singer in person at a concert — a moment that may have helped her work out Olivia’s routine and whereabouts.

The court made its ruling official earlier this month, but it was Low herself who first shared the verdict, oddly enough, by posting the judgement on both her Instagram and Facebook accounts on 11 June.

As for Olivia Tsao, she took to Instagram Stories that same day, expressing relief that the ordeal was finally behind her.

“This is the most comforting news I’ve received in a while. Thank you everyone for your concern,” she wrote. “I also want to thank my friends who supported me through this, and my lawyers for their patient help. I still consider myself a very lucky and happy person.”

Though Olivia hasn't said more publicly since, fans online have praised her for staying calm and professional throughout a clearly unsettling situation.

With Taiwan now stepping up on anti-stalking laws, this case might just mark a turning point in how celebrities are protected — both online and off.
