Hence, the business activities will be suspended at the mall, temporarily.After visiting the spot, BBMP Commissioner Manjunath Prasad told mediapersons that "Prima facie, water from the AC duct pipe had collected in the floors resulting in accumulation of moisture in the wall. This led to a portion of the ceiling wall caving in. But will have to investigate, thoroughly," said the commissioner.The mall was built around 15 years ago and it is crucial to understand the building bye-laws followed by then structural engineers who worked on the mall, said Prasad adding that the Palike engineers will ascertain the quality of construction materials used for the mall.Mayor Padmavathi visited the spot and gathered details about the accident. Speaking to the media, Mayor said even the sidewalls too have developed cracks. Keeping this in mind, business at the mall won't be allowed to continue for the safety of the people. "Mall will be shut down for temporarily," said the Mayor. On allegations of sub-standard work, Mayor refused to say anything. "We will investigate into the accident, first," she added. Meanwhile, fire tenders have rushed to the spot and have barricaded the area, completely.It may be recalled here that a 45-year-old housekeeping staff sustained injuries after a portion of ceiling of the mall's rear wall came off on Monday. Following the incident, mall personnel quickly evacuated the people from the mall. Movie shows were cancelled and the mall was quickly cleared.
