A major slab collapse in a dilapidated building in Nalasopara East left a mother and her teenage son stranded on the fourth floor late Tuesday night. The duo was safely rescued by fire brigade officials of the Vasai Virar City Municipal Corporation (VVCMC) using a ladder.

The incident occurred around 10 PM at the Sai Simran Building in the Achole area. The slab of the hall in flat number 404 gave way, and the debris crashed down onto the third floor, trapping Mansi Dilip Patel (47) and her son Aarush Dilip Patel (14) in the kitchen.
