Owner of Dominican nightclub whose roof collapsed and killed 236 people arrested

The owner of a nightclub in the Dominican Republic, whose roof collapsed in April and killed 236 people, was arrested Thursday along with his sister.

Antonio Espaillat and Maribel Espaillat have not been charged in the case, although authorities have 48 hours to present any charges before a judge.

"Both defendants displayed immense irresponsibility and negligence by failing to physically intervene to prevent the club's roof from collapsing, as it ultimately did, causing 236 deaths and more than 180 injuries," the Dominican Republic's Attorney General's Office said in a statement.
