New Delhi, June 8 -- A couple from Kolkata in West Bengal was arrested on Sunday in connection with the murder of a 45-year-old assistant professor of a Delhi University college, whose body was found at a high-rise society in east Delhi's Vasundhara Enclave on Thursday. Joint commissioner of police (eastern range) Ajit Kumar Singla said the motive behind the murder was a property dispute and that the couple, who travelled to Delhi, murdered the professor and returned to Kolkata, are distant relatives of the deceased. The woman was found with severe head injury, both her wrists slit and she had bruises on her face and body, suggesting that a scuffle had taken place, according to investigators familiar with the probe details. The arrested couple were living as tenants in one of her ancestral properties in Kolkata and wanted to buy it, DCP (east) Rajiv Kumar said. "The couple saw her as the main hurdle. Enraged because the professor was not giving her consent despite their repeated requests, they travelled to Delhi, killed her on Wednesday, and returned to Kolkata," Kumar added....
