On August 10, ONF held the group's comeback online showcase for the group's fifth mini album 'SPIN OFF'.
Soon after the showcase ended, ONF's management agency WM Entertainment shared an announcement.
They continued, "After these fans snuck into the venue, they filmed the rehearsal, got their hands on confidential documents, ate catered food and even hid in the restroom."
Lastly, they added, "As all staff wore a face mask in prevention of COVID-19, it made it difficult to identify them sooner. We will make sure this does not happen again. We sincerely apologize for not being able to prevent such fans from causing trouble."
