Hours after triple murders in a south Delhi locality, a first-year polytechnic student was arrested on Wednesday by Delhi Police for murdering his parents and sister in a fit of anger.
"The accused has been identified as Suraj, 19. He was arrested after he confessed to his crime. He was repeatedly changing his statements which did not match with the evidence found from the spot," Deputy Commissioner of Police Devender Arya said.
Mithilesh and Siya, a couple in their 40s, and their daughter Neha, 16, were found dead in a Vasant Kunj area in early morning hours.
"During the investigation, Suraj cooked up a story. He showed himself as a victim and informed his neighbours that some robbers had barged from an adjacent building into his house. They attacked him with a heavy object making him unconscious," Arya said.
"When he came to, he found his sister and parents dead with multiple stab injuries. He raised alarm and informed his neighbours --Pinto and Atul," the officer said.
The neighbours told the police that they heard Suraj, 19, crying for help from the balcony of their apartment on the first floor.
"He was heard shouting that masked robbers had attacked his family members and ransacked it," the officer said.
"A first-year polytechnic student from a Gurugram private college, Suraj was found changing his statements. On sustained interrogation, he broke down and confessed to his crime. He said his parents and younger sister teased him for studies. His father often beat him up for his bad habits," he added.
"From footage of a CCTV installed near the residences and a shop, the police team found a girl and youth walking around the street. The youth was waiting for someone for an hour around 1 a.m. They could be involved in helping the accused. Efforts are on to identify them," he said.
The police are also checking Suraj's phone and laptop.
