孟加拉警方逮捕发生火灾的工厂官员

Authorities in Bangladesh have arrested three factory officials in connection with a fire Saturday that killed at least 110 people.

The police chief in the capital, Dhaka, said the officials were arrested Wednesday amid allegations that managers told employees to return to work after fire alarms rang, and that locked doors trapped workers inside.

Hundreds of workers were unable to get out of the fashion factory as the fire burned. Fire officials say a lack of emergency exits contributed to the number of deaths.

Thousands of workers protested for a third day Wednesday, blocking streets and throwing stones at buildings.
