Nguyen Trung Hieu (Chi Dan) was just prosecuted for the crime of organizing the illegal use of drugs. Meanwhile, Andrea Aybar Carmona - a former model with Spanish nationality - was prosecuted for two charges including organizing the illegal use of drugs and illegally possessing drugs.
Although they have never publicly mentioned each other, Chi Dan and Andrea Aybar Carmona have participated in many activities together.
When both were prosecuted, a photo recording the moment Chi Dan and An Tay went to watch basketball together in 2022 was "dug up" and shared on social networks.

Besides, many people also realized that An Tay was following Chi Dan's personal account on Instagram.
An Tay also appeared and happily put her arm around Chi Dan's shoulder in a music video released in 2023.

According to information from the investigating agency, Le Thi Trieu, Nguyen Trung Hieu (alias Chi Dan), Nguyen Trung Tin, Hoa Thi Hong and Thai Thi Huyen had previous acquaintances.
On November 4, 2024, at a house in Tan Binh district (old), Hieu invited a group of friends to use drugs together and everyone agreed and agreed to contribute money to buy together.
This group then ordered about 5g of ketamine and 3 MDMA pills for 3 million VND to use. After using up ketamine, the subjects continued to use "happy water" drugs, then ordered 2 more packages of "happy water" worth 7.1 million VND and 2.5g of ketamine worth 2.5 million VND. On November 7, 2024, the actions of the whole group were discovered by functional agencies.
Regarding Andrea Aybar Carmona (model An Tay), from 2020, this person hired Van Anh Duy as a personal assistant, in charge of supporting video recording for posting on TikTok as well as picking up and dropping off at work, with a salary of about 10 million VND per month.
At the beginning of 2024, Andrea Aybar Carmona repeatedly asked a man named Loc to buy drugs for use, with the source of purchase from a person named Ngoc in the Bui Vien area. Not only using alone, Andrea also used it together with Loc and assistant Van Anh Duy in the apartment, even at times adding a friend known as Nguyen Phuong Dong to participate.
On November 8, 2024, when continuing to ask to buy drugs for use, the incident was discovered; functional agencies searched and seized a small amount of methamphetamine and marijuana at Andrea's residence.
