A devastating gas blast allegedly triggered the collapse of a ground-plus-two-storey chawl in Bandra East on Friday, injuring 15 people.

Two patients sustained severe burn injuries, while one patient with minor bruises was treated at Bhabha Hospital’s OPD and discharged. “Rehana Ansari, 65, has burns all over her body except her chest and stomach. Though her burns are superficial, her heart condition and diabetes make this a serious case,” said Dr Smit Patel, medical officer at KEM Hospital.

“Her husband, Mehmood Ansari, has more severe burns, 58 per cent, and while he has no comorbidities, his obesity complicates treatment. Both have been cleaned, given full-body cold water baths, and their burns are being dressed systematically,” he added.
