The police identified the deceased as Mohammed Wasim of Loni,Ghaziabad; Imran of Mauzpur in Delhi and Shekhar Sharma,a resident of Dankaur. The police said all three were in their early-20s. Shankar Dutt,27,the personal assistant of Noida and Greater Noida Authority CEO Mohinder Singh,was abducted near Noidas Pari Chowk around 7 pm on Tuesday. The police today said the assailants had made ransom calls from Dutts cellphone to his home in Moti Bagh,South Delhi and demanded Rs 10 lakh. On Wednesday,Dutt said he was waiting for a bus when the trio arrived in a car (an Indica) and forced him in: They beat me and tied my hands. Blindfolded,he was put in the leg space of the backseat. Senior Superintendent of Police (SSP),Gautam Budh Nagar,Ashok Kumar Singh said it is suspected the trio first abducted Dutt to rob him but later realised he was an official of the Greater Noida Authority and thus made the ransom call. After Dutts family called the police,Dutts mobile number was put on surveillance,Superintendent of Police (City) Ashok Tripathi said. Police traced their location to the Delhi-Noida border. While police in Noida,Greater Noida and surrounding areas were alerted,the police suspected the car they were looking for was a white Indica when it sped off when asked to stop for checking.

S K S Pratap,SHO of phase II police station,who was part of the team,said the police were not certain till then that the car was carrying Dutt. After shooting the criminals we found a man in the car,tied up.
