Police have registered a case against six persons, including two brothers, for allegedly cheating a 71-year-old man in Maharashtra's Thane city to the tune of Rs 1.28 crore on the pretext of involving him into their business, an official said on Thursday.

In his complaint, the septuagenarian man alleged that he was wooed into joining their work of changing the tyres of cars owned of a prominent company and was promised lucrative returns, following which he paid money in several tranches over the past few years, he said.
