Families struggled Saturday to identify the bodies of relatives killed in a Buenos Aires nightclub fire that left at least 186 people dead, many after being trapped inside by locked emergency exits.
The club's owner, Omar Chaban, was being held by authorities pending an investigation into Thursday's inferno. Judicial officials said they were looking into claims the building was overcrowded at the time of the blaze, which also injured over 700 people.
Authorities raised the death toll from 175 after 11 more deaths were reported. Some 100 people remain in critical care in city hospitals, and police warned the death toll could rise.
Investigators said they believed one of Argentina's worst disasters began when somebody set off a flare during the concert, igniting the foam ceiling of the Cromagnon Republic club while it was crowded with about 4,000 mostly teenage fans of the Argentine rock band Los Callejeros. The building had a capacity for some 1,500 people, city officials said.
