Hathras (Uttar Pradesh), Dec 23 (TIWN) Key accused Sandeep Sisodiya in the alleged gang rape and gruesome murder of 19-year-old Dalit girl from Uttar Pradesh's Hathras, was frustrated after the victim ignored him, the charge sheet filed by the Central Bureau of Investigation (CBI) has said.

In the 19-page charge sheet filed before a local court, that IANS has accessed, claimed that Sandeep and the victim had developed acquaintance two or three years back, which gradually developed into a "love affair".
