A Delhi resident was hacked to death by unidentified persons in a lodge in Tirupati. Four days ago, a man and woman claiming themselves as husband and wife took a room in the lodge. The couple informed the lodge supervisor that they came to Tirupati for Tirumala visit. The lodge organisers informed the police about the murder. The police visited the murder spot and sent the body to a government hospital for post-mortem. Cops are suspecting extramarital affair might have led to the murder.
