JoongAng Daily:

The Seoul Metropolitan Police Agency yesterday applied for an arrest warrant for the head of an importing company, surnamed Lee, 32, for bringing in the faulty auto refrigerant from China.

The police are also investigating 11 dealers who bought the refrigerant from Lee. The police believe Lee imported the cheap refrigerant because refrigerant prices doubled in price in Korea as the weather got hotter.

Lee sold 41 tons of the 50 tons brought in from China, which were 40 to 60 percent cheaper than legitimate brands, authorities believe.
