Police raid Jeju Air offices after crash killed 179 people in South Korea; airline CEO banned from leaving country

South Korean police raided the offices of Jeju Air and the operator of Muan International Airport Thursday as they step up a probe into the fatal crash of a Boeing 737-800 that killed 179 people.

The flight was carrying 181 passengers and crew from Thailand to South Korea on Sunday when it issued a mayday call and belly-landed before slamming into a barrier, killing all aboard except two flight attendants.

Authorities on Thursday carried out search and seizure operations at Muan airport where flight 2216 crashed, a regional aviation office in the southwestern city, and Jeju Air's office in the capital Seoul, police said.
