Parminder Singh was working as an accountant with Himanshu Sabharwal, the son of Prof Sabharwal. Himanshu has alleged that the men behind his father's murders have killed Parminder too.
Parminder Singh along with Himanshu was putting up posters in the Delhi University (DU) campus for a candlelight march to protest against the acquittal of the six accused Prof Sabharwal's murder case on Thursday, Jul 22 night.
Since Himanshu was the last one to have been with Parminder Singh, Delhi police has arrested him for an inquiry.
