Eight people posing as income tax officials recently raided the home of an imitation jewellery businessman in Sion and seized Rs 18 lakh. The police arrested the suspects, including Rajkumar Gujjar, a friend of the businessman’s grandson, who was told by one of the gang members that Sushant Lohar, the main accused, was in the I-T department and providing a tip for a raid would fetch a 10% commission. Gujjar informed the gang that the family of businessman Ram Kuber Patwa had received Rs 10 crore in cash as part of a property deal.
