"We have announced Rs one lakh cash award for information leading to the arrest of the suspect," Joint Commissioner of Police B K Singh told PTI here, as the assailant is on the run two days after the brazen attack, caught on CCTV footage, sparking public outrage.

Asked about reports that the mobile which the assailant took away from the victim after leaving her in a pool of blood was traced to Hindupur in Andhra Pradesh, Singh said, "There is no truth in it."
