According to the city's Special Judicial Police Bureau for Public Safety, more than 5,000 pieces of counterfeit designer goods valued at 3.9 billion won ($2.5 million) have been confiscated.

Manufacturing, selling, or holding onto counterfeit goods is punishable by imprisonment of less than seven years, or a maximum fine of 100 million won.

Those booked were found to have manufactured, sold, or stored 5,006 pieces of counterfeit clothing, handbags, and golf gear.

Those items include more than 2,700 pieces of clothing with an estimated value of 1.7 billion won, jewelry with a combined value of 1.17 billion won and 191 handbags valued at 450 million won.
