The 'Tien S Catcher' fishing vessel, which was engaged in towing operations off the coast of Busan, capsized and sank on September 2nd. Only one out of eight crew members was rescued, while the remaining seven are missing. The Coast Guard has been searching for the missing persons using patrol boats for four days and has also conducted nighttime searches, but no missing persons have been found yet. Due to strong winds and high waves, search operations are facing difficulties, and underwater searches of the sunken hull are currently impossible. The Coast Guard plans to switch to daytime searches from the 5th and continue the search by reinforcing equipment.
