Warehouse owners and traders of Khatunganj were seen dumping hundreds of sacks of rotten onions in what is the country's biggest wholesale market for commodities, but prices of the spicy bulb remained sticky upwards at retail level. 

As onion prices spiral out of control fuelled by a supply shortage, a huge amount of rotten onion was found to be dumped in Chaktai canal adjacent to Karnaphuli River on Saturday morning.
