Lucknow | The Lucknow Development Authority (LDA) has issued a demolition notice for the Aliganj building where a fire claimed 15 lives a day ago, officials said on Tuesday.

Authorities have also launched a crackdown against its own officials in connection with the illegal operation of the residential building as a commercial space.

The three-storey building was issued a demolition order in 2016 over unauthorised construction but it was revoked less than two months later.

"We have once again issued a demolition notice over (construction) violations for the Aliganj building where the fire incident took place on Monday," LDA Vice Chairperson Prathamesh Kumar told PTI.

"We have also initiated inquiry against officials for laxity and action will be taken against them," Kumar said. The process to identify such officials and their role in the negligence has begun.

The massive fire broke out on Monday afternoon in the three-floor commercial building housing an animation centre, killing at least 15 people, mostly students, and injuring nine others.
