A 26-year-old Australian man, Johnson Wen, was sentenced to nine days in jail for causing public nuisance during the premiere of the film Wicked: For Good in Singapore. District Judge Christopher Goh labeled Wen's behavior as "attention-seeking," asserting that he mistakenly believed his actions would go unpunished in Singapore. The incident garnered widespread media attention and public outrage, with many condemning Wen's actions as disrespectful and traumatic to the star, Ariana Grande, who was visibly shocked during the event, according to Channel News Asia, South China Morning Post, and BBC.

The disruption occurred on November 13, 2023, at Resorts World Sentosa, where Wen jumped over a barricade and grabbed Grande while jumping up and down, leading to immediate intervention by co-star Cynthia Erivo and security personnel. The prosecution highlighted that Wen had a history of intruding at significant events, such as concerts by Katy Perry and The Weeknd, showcasing a pattern of behavior that prompted the call for a substantial deterrent sentence. This led to Wen's arrest the following day, as multiple videos of the shocking incident circulated on social media, according to Channel News Asia and South China Morning Post.

During the court proceedings, Wen expressed remorse and claimed he would refrain from similar actions in the future, stating, "I won't do it again, your honour." However, the court observed that Wen's conduct was premeditated and intentional, aiming to gain attention. Judge Goh remarked on the potential risks associated with Wen's actions, noting it was fortunate no harm had occurred, underlining the importance of accountability for reckless behaviors in public spaces, according to Channel News Asia, South China Morning Post, and BBC.

Despite no actual harm being reported, the prosecution argued that Wen's actions warranted a custodial sentence as a warning to deter similar conduct in the future. The courts highlighted the psychological impact on Grande, who has publicly addressed her struggles with post-traumatic stress disorder from past traumatic events. This aspect added weight to the argument for significant penalties against Wen for his intrusive behavior, according to Channel News Asia, South China Morning Post, and BBC.
