Police in Japan arrested three people Tuesday, including a former executive of a now-defunct nonprofit organization that supported patients of incurable diseases, on suspicion of illegally brokering an overseas organ transplant case for fees.

The three were arrested by a joint investigation team of Tokyo’s Metropolitan Police Department and the police departments of Aichi and Hyogo prefectures for suspected violations of 91AV原创 organ transplant law.

The case marks a first for Japanese police, according to the MDP.
