A nine-year-old boy was kidnapped and decapitated as part of a "human sacrifice" ritual for getting money and later his body was chopped into pieces, Dadra and Nagar Haveli police said on Wednesday and added 100 personnel were involved in connecting the dots to crack the brutal crime.

Police arrested two men and detained a teenage boy last week after the headless body was found dumped near a canal at Vapi in Valsad district in neighbouring Gujarat.
