Police on Friday conducted an additional raid on Lim Hyun-taek, the president-elect of the Korean Medical Association (KMA), who is accused of having instigated collective resignations by junior doctors.

The Seoul Metropolitan Police Agency said it additionally seized Lim's mobile phone and sent investigators to his office in western Seoul and his residence in Asan of the central province of South Chungcheong.

The police agency seized Lim's phone in their previous raid in March, but it was confirmed to have been used by him in the past.

Lim has been under a police probe after the Ministry of Health and Welfare filed a complaint alleging he violated the medical law by inciting collective actions by trainee doctors opposed to the government's plan to sharply increase medical school admissions.

Over 90 percent of the country's 13,000 trainee doctors went on strike in late February to protest the planned increase in medical school admissions. (Yonhap)
