Gurugram, July 7 -- A man convicted of murdering his girlfriend was arrested from Chander Vihar in Mandawali, Delhi, after remaining on the run for nearly 20 years, Faridabad police said on Monday. The 47-year-old, who is from Delhi's Pandav Nagar, had allegedly changed his identity and appearance by growing a beard and hair, avoided social media and smartphones, and took low-profile jobs to evade arrest. He was working as a security guard when he was arrested on Saturday, police said. According to police, the Sector 65 crime branch unit headed by inspector Joginder Singh had been tracking him for the past year. He was produced before a Faridabad court on Sunday after questioning and sent to judicial custody. A crime branch official said the convict shot dead his girlfriend in Surajkund on April 19, 2001, following a dispute in their relationship. He was arrested on April 29, chargesheeted, and on July 10, 2002, a Faridabad sessions court convicted him under IPC Section 302 and the Arms Act, sentencing him to life imprisonment and imposing a Rs.20,000 fine. Police said he later challenged the conviction in the Punjab and Haryana High Court, which granted him bail in May 2006, after which he absconded. Officials said the high court later rejected his regular bail application and remanded the matter to the lower court, which issued an arrest warrant. Yashpal Yadav, public relations officer of Faridabad police, said the convict stayed at his Delhi residence for some time before becoming untraceable. "Court and police came to know that he was on the run only after he started skipping his appearances during hearings, following which an arrest warrant was issued but could never be executed over the next two decades," he said....
