YouTuber“新宿109 KENZO”因诽谤京都高管被捕，该高管后自杀身亡。

KYOTO (TR) – Kyoto Prefectural Police arrested a popular vigilante YouTuber on Thursday on suspicion of defamation after he posted a video labeling a Kyoto real estate executive a “scammer.”

Takuma Nakano, the real estate executive based in Kyoto City’s Sakyo Ward, died in a suicide just a month after the video went live, reports Jiji Press (Oct. 14).

Miki Ikeda, a 28-year-old resident of Tokyo’s Nakano Ward who operates under the moniker “Shinjuku 109 KENZO,” boasts over 1.03 million subscribers on a channel dedicated to “eradicating fraud,” having uploaded more than 700 videos.

Upon his arrest, Ikeda withheld cooperation, telling investigators, “I will speak after I talk to my lawyer.”

According to the Sakyo Police Station, Ikeda is accused of uploading a video around June 14 of last year that featured an image of Nakano, then 36. The video featured inflammatory on-screen text reading, “The hidden face of a famous entrepreneur. A massive M&A scammer?”

Prior to his death, the targeted executive had consulted with police regarding the video. He passed away the month after the video was published, prompting his grieving mother to file a formal criminal complaint.

In a related development, Sakyo police also arrested two real estate company representatives on Wednesday on suspicion of attempted extortion. Makoto Akagi, 46, and Yuki Yasuda, 35, both residents of Okayama City, are accused of attempting to extort a 3 billion yen from a victim by threatening to distribute a similar defamatory video.

Because the video was posted on Ikeda’s YouTube account, investigators are now probing the extent of the relationship between the prominent YouTuber and the two alleged extortionists.

On Thursday, the mother of Nakano filed a lawsuit with the Kyoto District Court seeking approximately 230 million yen in damages from Ikeda and the two alleged extortionists. In the suit, she alleges that their actions, such as the posting of videos, led to her son’s suicide.

According to the complaint, Nakano became embroiled in a dispute with Akagi and Yasuda regarding the sale of a company he managed. Akagi allegedly requested that Ikeda create a video about the matter.

京都（TR）——京都府警方周四逮捕了一名颇受欢迎的网络义警博主，他因发布视频称京都一名房地产高管为“骗子”而涉嫌诽谤。

据时事通讯社（10月14日）报道，居住在京都市左京区的房地产高管中野拓马在视频发布一个月后自杀身亡。

居住在东京中野区的 28 岁居民池田美纪（Miki Ikeda）以“新宿 109 KENZO”的网名运营着一个致力于“根除欺诈”的频道，拥有超过 103 万订阅者，并上传了 700 多个视频。

池田被捕后拒绝合作，他对调查人员说：“我要先和我的律师谈谈，然后再说话。”

据左京警察署称，池田被指控于去年6月14日左右上传了一段视频，视频中包含当时36岁的中野的照片。视频屏幕上配有煽动性文字：“一位知名企业家的隐藏面孔。一个并购诈骗大亨？”

这名被指控的高管生前曾就该视频咨询过警方。视频发布一个月后，他便去世了，悲痛欲绝的母亲随后提起正式的刑事诉讼。

另据报道，左京警方周三逮捕了两名房地产公司代表，他们涉嫌敲诈勒索未遂。46岁的赤木诚和35岁的安田由纪均为冈山市居民，他们被控威胁散布类似的诽谤视频，企图向受害者勒索30亿日元。

由于该视频发布在池田的 YouTube 帐户上，调查人员目前正在调查这位知名 YouTuber 与两名涉嫌敲诈勒索者之间的关系程度。

周四，中野的母亲向京都地方法院提起诉讼，向池田及其两名涉嫌敲诈勒索者索赔约2.3亿日元。她在诉讼中称，他们的行为，例如发布视频，导致了她儿子的自杀。

根据起诉书，中野与赤木和安田就其管理的公司的出售事宜发生纠纷。据称，赤木要求池田就此事制作一段视频。
