South Korean police yesterday arrested a younger brother of the country’s most wanted man, a businessman linked to a ferry disaster in which hundreds of school children drowned, as authorities cast a wide net for the fugitive’s family.

Prosecutors have indicted the captain of the sunken South Korean ferry and three crew members on homicide charges, alleging that they failed to carry out their duties to protect passengers.

Frustrated relatives of the scores still missing from the capsized ferry Sewol have staged a marathon confrontation with South Korea’s fisheries minister and the coastguard chief.
