Cooper Noriega, a TikTok star with more than 1.7 million followers on the app, has died at the age of 19.
He was found dead in Burbank, California, in the early hours of Thursday morning, the Los Angeles County Medical Examiner-Coroner’s Office said.
The cause of his death has not been announced and the matter is still under investigation.
Tributes have been paid to the teenager in the comments on his latest TikTok posts.
Noriega had made several videos about his struggles with mental health and addiction.
Last Sunday he announced he was starting a group for people to talk about their experiences with mental health on the messaging platform Discord.
He said: “I have just created a Discord server strictly for mental health because how much I love you guys, and how much I struggle with it myself. I want you guys to not be alone and feel safe.”
