On Sunday evening, the police arrested the building owner Rehan, along with his manager Furkan, and booked a case under Section 304 (punishment for culpable homicide not amounting to murder) of the Indian Penal Code.
Two brothers of Rehan - Imran and Shaan - were also questioned by the police since they own two-thirds of the property, police said.
It was Rehan, who manages the property, which was given on rent to around ten people who run various factories from the premises, police said. "It is a T-shaped building with one entry and exit facility. Over the years, Rehan purchased the houses behind this building. It is now a 600 sq m property in which the back gate exits are blocked due to illegal construction by other houses and factory owners," ANI quoted the official saying.
"Since the accident site is still very hot, forensic teams haven`t been able to collect samples properly. They will wait for a few more hours. To find out the electrical fault, electrical meters installed in the building will be checked," he added further.
