At 3 am in a swirl of fog, 20 men arrived at one of Chandigarh's biggest jewellery stores. They were in police uniforms, say the two guards who were on duty at the Tanishq showroom. CCTVs show the men entering the shop in the Manimajara area of the city early on Wednesday morning. But the monkey caps they wore make them unidentifiable. They left with Rs. 15 crore worth of jewellery.
