Not able to scrounge any leads even after four-months of investigation, the Delhi Police are now retracing their steps in the murder case of Parvinder Singh (31), a close aide of Himanshu Sabharwal. Singh was found stabbed to death near Khalsa College in Delhi University’s North Campus July 23 this year.
The police on Wednesday conducted a lie-detection or polygraph test on Sabharwal and his fiancée Garima.
Sabharwal is the son of slain professor HS Sabharwal, who was murdered in Ujjain in 2006.
The police said they have found over the course of investigation several inconsistencies in the statements given by Himanshu and others close to the victim.
The test was conducted at Central Forensic Science Laboratory (CFSL) in the CBI headquarters on Lodhi Road.
“This is a part of the investigation. Two people — Himanshu and Garima — went through the polygraph test. Others would also be questioned in the next two days,” said Deputy Commissioner of Police (North) Sagarpreet Hooda.
The police would also be conducting lie detection tests on two other acquaintances of Himanshu — Pooja Gaur, a documentary filmmaker and Mohammad Saif a third-year student of Ramjas College.
Himanshu however denied any inconsistencies in his statement. “There are no inconsistencies in my statements. We are co-operating with the police in every way possible. The test is just to rule out our involvement in the case.”
