Police arrested a Chinese Dragon member and three others from another gang over a raucous fight last year that broke out in a restaurant high up in a Tokyo skyscraper.

The Metropolitan Police Department believes the 42-year-old man is a senior member of the Chinese Dragon, a loosely organized crime group based in Tokyo.

The other three belong to Chukaryu, a similar group of mainly younger members based in Saitama Prefecture.

One of the three, in his 30s, is believed to be a senior member of the group.

The four suspects, along with a group of others, allegedly crashed a party held by members of the Chinese Dragon at a French restaurant on the 58th floor of Sunshine 60 in the Ikebukuro district on Oct. 16, 2022.

Their appearance turned the party into a scrap involving some 100 gang members at the restaurant, where they broke plates and caused damage to the business.

The party was being held to celebrate the release of their former leader from prison.

Police believe the group stormed the party because they were upset they were not invited.

Five other people from the group of party crashers were arrested in December 2022 and have already been released.
