Two builders, Jamil Qureshi and Salim Shaikh, were arrested yesterday in connection with the illegal seven-storey building that collapsed at Shilphata in Mumbra on Thursday.

According to the police, former scrap dealers Qureshi and Shaikh had constructed the illegal seven-storey building in partnership with five others. The building had been constructed on forestland in just three months, without the requisite permissions and certificates.
