The police report called the deaths a "mass killing." About 2,500 people were injured in the disaster.
Rana and the owners of the five garment factories are among the 41 defendants accused of murder. While Rana is in jail and 16 others are out on bail, the magistrate issued arrest warrants against 24 others, said police prosecution-wing officer Mohammad Asaduzzaman.
He said the police would take steps to arrest them. The court told police stations to submit updates on which arrests have been made when the court next hears the case on Jan. 27.
In a separate case, the accused are also facing charges of violating safety rules in the Rana Plaza building. The original five-story building was meant for office space and retail stores, but more floors were added illegally and transformed into factories.
The extremely low wages in Bangladesh led global brands and retailers to choose its garment industry over factories in China and other developing countries.
The building collapse triggered an uproar for reforms in a sector that helps the country earn about $25 billion a year from exports, mainly to the U.S. and Europe.
