Coast Guard investigating role of alcohol in Baltic Sea ship crash

The Swedish Coast Guard is investigating whether alcohol contributed to an early Monday morning cargo ship crash in the Baltic Sea.

A British citizen and a Croatian citizen have been detained as suspects in Sweden's preliminary probe into the collision, according to a Swedish Public Prosecutor's Office press release.

The Prosecutor's Office added that the preliminary investigation into "aggravated drunk driving," "gross negligence in maritime traffic," and "grossly causing another's death" is in an initial stage.
