DHAKA, Bangladesh — Criminal charges for ‘‘unpardonable negligence’’ should be brought against the owner of the Bangladeshi garment factory where a fire last month killed 112 people, according to a preliminary report from a government inquiry submitted Monday.

‘‘The owner of the factory cannot be indemnified from the death of large numbers of workers from this fire,’’ said Main Uddin Khandaker, the official who led the inquiry. ‘‘Unpardonable negligence of the owner is responsible for the death of workers.’’
