Police on Thursday arrested three urologists at a Tokyo hospital whose inexperience in a surgical procedure allegedly caused the death last year of a patient with prostate cancer.

Arrested on suspicion of professional negligence resulting in death were urologists Jun Madarame, 38, Taro Hasegawa, 34, and Shigetake Maeda, 32, of Aoto Hospital of the Jikei University School of Medicine in Katsushika Ward.

Police plan to turn over to prosecutors Friday their case against three other doctors involved in the incident: a 52-year-old head of the hospital's medical examination department and two anesthesiologists.
