PRAYAGRAJ, Oct. 31 -- Authorities tightened the cordon around a residential property in Baraipur Ramnagar village here on Friday as the excavation for a buried cash cache reportedly worth crores of rupees entered its third consecutive day. The high-profile operation follows the sensational Wednesday night recovery of three blue plastic drums packed with cloth-wrapped bundles of Rs.500 notes buried beneath the house. While the exact valuation of the seized currency remains tightly guarded, the Income Tax (I-T) Department formally took control of the site and the investigation on Thursday evening. Brothers Rakesh Yadav, alias 'Mahakal', and Rajesh Yadav, the owners of the property in the Ganga Nagar zone, have been handed over to tax officials for sustained interrogation. The residence has been turned into a virtual fortress, guarded round-the-clock by nearly 32 police personnel drawn from three local police stations. Inside the sealed premises, around a dozen labourers hired on Wednesday night remain at the site as digging continues. Investigators are also preparing to expand the search to adjacent orchards, vacant plots, and other real estate linked to the Yadav family.P7...
