Ukrainian captain arrested in fatal boat crash that left 7 dead, 21 missing: police

A Ukrainian man captaining a cruise ship that collided with a Hungarian sightseeing boat Wednesday night, killing at least seven people, has been arrested on suspicion of endangering water transport, police said.

The man, identified only as Yuriy C., was taken into custody on Friday after investigators said “material evidence” collected from the scene pointed to “reasonable suspicion” that the 64-year-old captain of the Sigyn “committed the crime of endangering water traffic causing a fatal mass disaster,” Hungarian Police said in a statement.

Further interrogation of the suspect led police to suggest that they initiate his “pre-trial detention.”

Police said Thursday that the small passenger boat, the "Hableany,” crashed with the Viking boat at 9:05 p.m. local time Wednesday night beneath the Margit Bridge.

"Both ships were heading north ... and when they arrived between two pillars of the Margit Bridge, for some reason the “Hableany” turned in front of the Viking ship,” Police Col. Adrian Pal said. As the Viking comes into contact with it, it overturns it and in about seven seconds, as it turned on its side, it sank.”

Video footage showed the two vessels traveling closely side by side as they approached the bridge. It was not immediately clear what caused the collision.

South Korea sent a team of 25 people, made up of members from the country's national fire agency, navy and coast guard, to help support Hungarian rescue efforts.

The victims were a group of tourists that left South Korea on May 25 as part of a group touring Europe, a South Korean travel agency, Very Good Tour, said. They were set to return on June 1.
