Bangladesh police arrest factory owner after dozens die in fire

Police chief says entrance was padlocked; separate inquiry looks into use of child labour at food plant

Bangladeshi police have arrested the owner of a factory where at least 52 people died in an inferno, as it emerged that children as young as 11 had been working there.

Police said the owner of the food factory and four of his sons were among eight people detained over the fire that broke out on Thursday and raged for more than a day. The blaze began in the evening at the five-storey Hashem Foods factory in Rupganj, just outside Dhaka.
