Mishra was arrested yesterday evening from his home in Lucknow and brought to Delhi on transit remand. He has been booked on charges of mischief by killing or maiming animal or cattle and relevant provisions of Prevention of Cruelty to Animals Act, the official said. On March 15, locals in Green Park area found three injured dogs and a dead puppy near the metro station and called police. Later, a video clip surfaced in which a man wearing a jacket and shorts could be seen attacking the dogs and a police team was formed to crack the case. Mishra’s identity was ascertained after local police conducted door-to-door search in all localities under the jurisdiction of Hauz Khas sub-division of Delhi Police and scanned through thousands of tenant verification forms, the official said. Once police zeroed in on Mishra, it emerged that he left his rented room at south Delhi’s Yusuf Sarai area after the incident and shifted to his maternal aunt’s residence in east Delhi’s Mayur Vihar where he stayed for around three days before leaving for his home in Lucknow. In the full video grab, he can be seen first feeding the dogs and then attacking them brutally in the staircase near one of the exits of Green Park metro station, the official added. Meanwhile, an animal rights body said Mishra should be awarded jail term at the earliest and psychiatric treatment should be provided to him. “Humane Society International (HSI) India had announced a reward for information leading to identification of the perpetrator. The organisation had received a call and worked with Delhi Police to track down the accused in Lucknow… HSI, India has demanded jail time and psychiatric intervention for the alleged dog killer,” it said in a statement. “We hope that there will be a speedy trial and he will be convicted soon,” said N G Jayasimha, managing director of HSI, India.
