New Delhi, Oct 3 : On the run after smothering his girlfriend to death at his rented home in Dwarka nearly 10 days ago, a 28-year-old man has been arrested in Dibrugarh in Assam, Delhi Police said on Saturday. Satish Kumar, son of a retired Army personnel, had allegedly murdered Dishu Kumari after a fight over sharing of a password of her mobile phone. Police said Satish and Dishu were colleagues at a Gurugram BPO. On September 23, the woman had come to Satish's accommodation in Chhawla. "He grew suspicious as the woman was getting calls from another person while she was with Satish. He asked her to unlock her phone to check the call details. Both had a heated argument, after which Satish smothered the girl to death. He later hid the body inside a bed and fled," said DCP Dwarka Santosh Kumar Meena. The body was discovered two days later after neighbours complained of foul smell from the room and called police. The accused also took away the woman's mobile phone and threw it into bushes near Greater Kailash. He also sold his mobile phones to avoid tracing by police and fled to Dibrugarh, from where he was finally arrested. /IANS
