Amritsar, Aug 19 - Three people were arrested for allegedly murdering a 22-year-old man and tying his body to a tree because he was planning to elope with a woman in their family, the police said here Wednesday.

Officials said Harpreet Singh, who ran a car accessory shop in this holy city of Punjab, planned to elope with his 20-year-old girlfriend, a resident of Boparai Baaj Singh village nearby, Monday night.
