Days after the Civil Lines police booked Vansh Bassi, son of former Amritsar Improvement Trust chairman Dinesh Bassi, in an alleged Rs 50-lakh property fraud case, the police detained the latter for questioning on Monday.The detention triggered a protest by Congress councillors and leaders, who demonstrated outside the Civil Lines police station. Amritsar MP Gurjeet Aujla also reached the spot and termed the action politically motivated.Aujla alleged that the Punjab Police was working under political influence and that Bassi was being targeted as part of a conspiracy. Congress councillors raised slogans against the police and said they were pushed out of the police station.Congress leader Sanjiv Tangri said the party would launch a massive agitation if Bassi was not released. “Even though he was not involved in the case, he has been deliberately targeted,” he alleged.The Civil Lines police had earlier booked Vansh Bassi and his alleged associate, Amit Bajaj, for allegedly duping a city resident of Rs 50 lakh in a property deal.
