00:00The police have confirmed that one of the main purposes of the investigation is to excavate
00:12the land around the area, so the police confirmed that there was an activity of excavating the
00:22land before the incident, and the purpose of the excavation is to replace the demolition
00:34pipe which is more or less 30 meters from the explosion site.
00:42So, the police have identified the developers, contractors, subcontractors and involved workers
00:54who used two generators, one is a backhoe and the other is an excavator, which was used
01:02to dig the land in the area to replace the existing demolition pipe.
01:08And the work was stopped on March 30.
01:14So, the results of the police investigation found that one of the excavators placed there
01:26sank into the hole.
01:30Is this excavation activity can cause the explosion?
01:40Is there anything that needs to be investigated further to determine other things that need
01:48to be collected when we dig that hole and find other physical evidence that can be
01:56collected?
01:58Is there any activity that can cause an explosion on the gas pipe?
02:06So, we still need time to find this out.
02:12We can confirm that there is an activity of digging the land, but how deep and how far
02:22needs to be investigated further.
02:26And then we need to confirm whether the activity can cause the explosion.
02:32So, the police need more time.
02:36At this time, we have interviewed as many as 56 witnesses from the victims who saw or
02:46saw the explosion.
02:54At this time, we have identified a witness who was at the scene at the time of the explosion.

03:08It means that within a distance of 30 meters from the explosion site, he was at the time
03:12of the explosion and he was also injured.
03:14So, the police are collecting information or information from this witness in order to
03:22find out if there is any activity of the fireman or any other activity that can cause an explosion.
