The Pune Metropolitan Region Development Authority (PMRDA) demolished an illegal six-storey building at Survey No. 45/1/2 in Marunji on Thursday.

Authorities said the action is part of a wider campaign against unauthorised structures based on recent surveys and complaints.

Deepti Suryawanshi-Patil, deputy collector, PMRDA anti-encroachment department, said, “The action was taken due to growing concerns over safety and illegal construction in fast-developing areas of the metropolitan region.”

A recent PMRDA survey revealed 967 unauthorised hoardings across its jurisdiction and 122 has been removed in Haveli, Bhor, Mulshi, Purandar, and Daund in the last few days, officials said.
