According to the report, the underage fan reportedly assaulted the group when he asked to take a photo with them.
Jessi was assaulted by a man named A who was nearby. CCTV footage showed Jessi trying to stop A, but quickly leaving the scene.
Police who were dispatched found Jessi and her group in the neighborhood and asked about the whereabouts of the assailant, Mr. A, but he said he did not know them. After the victim was diagnosed with a concussion, the assailant, including an unknown assailant, was arrested on the 10th.
In response to allegations that she did not take any proactive measures and simply stood by and watched the assault, Jessi posted a comment on her SNS on the 12th.
However, Jessi explained that the incident was committed by someone she had never met before. "I was overwhelmed by the sudden situation and was not able to give my fans the proper consideration. Regardless of the circumstances, I will not tolerate anyone else's actions.
We feel extremely sorry and morally responsible for causing such sudden harm to our fans."
After terminating her exclusive contract with the management office DOD, Jessi was arrested at the Seoul Gangnam Police Station on the 16th.
She turned herself in to the police and was questioned about the incident. The assailant, Mr. A, is a Chinese acquaintance of Jessi's producer, and left the company after the incident. During the police investigation, Jessi said, "I have no relationship with the assailant."
"They are Chinese friends of a close producer of mine," he said, but some have even claimed that the perpetrators were a "Korean gang," sparking controversy.
On the 23rd, Jessi apologized for the second time after confessing that she had been the victim of serious malicious comments. Jessi said, "I regret it thousands, tens of thousands of times. I want to go back to that time.
"I would be happy if I could be forgiven with just one word," he said, "I know that I cannot be forgiven with just one word. However, I will do my best to correct my mistake and help the victim recover. It's very late.
I apologize for the inconvenience, but I ask for your forgiveness once again. I was wrong."
