Speaking to reporters on the same subject, Manoj Yadava, Haryana police chief, said: 

It was basic policing skill that our brave Constable Ravinder Singh displayed before losing his life. He had scribbled the vehicle number on his hand which was noticed during the post-mortem. 

Ravinder Singh and Kaptan Singh were found lying in a pool of blood last Tuesday. The inquiry suggested that they had seen the accused drinking in a car parked on the side of the Sonipat-Jind road. After trying to stop them drinking, they were attacked with sharp weapons, leading to their deaths.
