Search efforts on the sunken Sewol-ho ferry have once again been hampered due to poor weather conditions.
A heavy wind watch was issued on Sunday morning in waters off of Korea's southwestern coast, which includes the accident site.
It's the latest setback for divers tasked with searching inside the ferry, who have been kept out of the water since the wee hours of Saturday morning.
In their place, around 20 submarine ships using sonar radars are conducting most of the searches, looking for bodies that may have been swept out of the ferry.
One of the floating buoys set up by authorities to track currents in the area was found as far as 35 kilometers away from the ferry site.
Prime Minister Chung Hong-won visited the ferry site on Sunday afternoon.
He vowed to provide special aid to the residents of Jindo island who have helped with the search and rescue efforts at the expense of their own livelihoods.
Investigations into the ferry sinking also continue.
Prosecutors have arrested a senior official of an inspection company on charges of negligence.
They say the inspector provided a false report on the condition of the ferry's life boats.
The official in question submitted a report to the Korean Register of Shipping saying that equipment in 17 categories on the Sewol-ho ferry was in "good" condition.
But only one out of 44 life boats deployed when the ferry began listing.
Prosecutors are also zeroing in on the de facto owner of the ferry operator, Yoo Byung-eun and his family to determine whether there were any business irregularities that could have led to the ferry sinking.
Yoo's brother appeared for questioning on Sunday.
He was paid monthly expenses of more than 2-thousand U.S. dollars in business consultation fees by Chonghaejin Marine Company, the operator of the Sewol-ho.
It represents the first time a family member of Yoo's has shown up for questioning.
Yoo's eldest son has been summoned to appear on Monday.
