A police team on Sunday seized Rs 93 lakh in cash in three raids, including one on a postal department clerk's house, in Jharkhand's Dumka district, police officials said.The officials said the raids were conducted at three places in the district.Police seized Rs 45 lakh from the house of Vinay Kumar Sigh, posted as clerk in Dumka Post Office, a senior officer confirmed.Two more seizures of Rs 31.50 lakh and Rs 16.50 lakh were made from the possession of two 'Patwaris' (land record keepers) -- Sunil and Shibu, respectively.The raids were conducted on a tip-off, the officials said, adding that it was surprising to find such a huge amount of money in the possession of a post office employee.They said that they were trying to ascertain whether money was given to the clerk for exchange or any other purpose.Until now, in Jharkhand, police have seized more than Rs 1.75 crore since the demonetisation of Rs 500 and Rs 1,000 currency notes announced by Prime Minister Narendra Modi on November 8.
