The Jamia Nagar police, however, denied that there was any delay in lodging the FIR.

"We carried out intensive search of the place where the firing took place near Gate number 7 (of the varsity). We found no empty cartridges there. We are, therefore, probing further to identify the accused and verify the crime. The FIR was lodged after due procedure," in-charge DCP, South East, Gyanesh Kumar said.

The Jamia Nagar police stated that a few persons approached them during the registration of the FIR saying they had seen the red scooter that was allegedly used for the crime.
