A day after apprehending two juveniles for allegedly killing 77-year-old real estate businessman at his Civil Lines residence in North Delhi and robbing Rs 11 lakh, police said one of them used to work at the victim's house but was fired over allegations of theft and he wanted to take revenge. Special CP (law and order of North zone) Dependra Pathak said the juvenile was working at the man's house as a domestic help two years ago, after his father, who also had worked there as a driver, recommended his name. After he was fired, he wanted to take revenge as well as earn quick money, Pathak added. “He along with his accomplice, also a juvenile, killed the victim, Ram Kishore Agrawal, on May 1. He was traced after scanning footage from hundreds of CCTV cameras and tracking his Metro card,” he said, adding that they have recovered Rs 10,37,000, jewellery and a mobile phone purchased from the stolen amount, along with a stolen motorcycle. Police received a PCR call about the murder at 6.52 am on Sunday. “His son told police that he found his father with his throat slit, around 6.40 am. He was rushed to a hospital where doctors declared him dead on arrival. We found that he had four knife injuries on his body,” said DCP (North) Sagar Singh Kalsi had said. During questioning before counsellors, the juvenile, who according to police is the main mastermind, claimed to have hatched the plan. “He (the former help) wanted to earn easy money and sensed an opportunity as he was aware of details of this family. He roped in his friend from his village and started planning meticulously to commit a fool-proof crime,” Pathak said. Police said a few days ago, the juvenile told his father that he got a job as a waiter in a restaurant and had to move to his friend’s flat to live closer to his new workplace. “On April 26, he left home and started living with his friend in a park. They watched YouTube videos on how to steal a bike without keys… and stole a motorbike. They later purchased toy pistols and two knives,” Pathak said. Police said after allegedly killing the victim, they took a bath in the Yamuna and destroyed their blood-stained clothes. “They had also rented a room for Rs 1,700 to keep the looted items. The former house help got a tattoo and bought his accomplice a phone using the money,” said an officer. The district police has also decided to move an application seeking transfer of the case from the juvenile board to a Delhi court to treat the duo as “adults” for the crime. Special CP Pathak said they are moving an application before the court concerned.
