4 Hathras accused taken to Guj for polygraph test, brain profiling

The four accused in the alleged Hathras gang-rape and murder of the 19-year-old Dalit girl were taken to Gujarat for a polygraph and brain electrical oscillation signature (BEOS) profiling on Saturday. It will take around a week to complete both tests on the four accused- Sandeep, Ravi, Ramu and Lavkush, who were arrested before the death of the victim in Delhi's Safdarjung hospital on September 29.
