Police have arrested the owner of the firecracker storage unit in Bawana where 17 people were killed in a massive blaze on Saturday. Manoj Jain, who ran the factory, has been arrested. A probe revealed it was a factory of "cold firecrackers" used in stage shows and Holi celebrations, said Rajneesh Gupta, Deputy Commissioner of Police (Rohini). Firecracker packages found at the site suggest the same, he said.
