The statement added that CCTV footage showed the miscreant in the get-up of a delivery boy with a helmet and three bags on his bike, due to which its number plate was not visible.
"Police have taken away the bullet, while pieces of a glass bottle are still there," it said.
According to a university official, the incident occurred around 9.30 am.
"The man came from the Okhla side, probably after committing a similar act at Shaheen Bagh. He hurled a bottle at the tent near Gate No. 7," he said.
The tent was empty since the students had suspended the protest.
As the tent did not catch fire, the man allegedly tried to set it ablaze using a lighter and fired a few rounds, the official said, adding,
"We informed the police about the incident and handed over the CCTV footage to them." He said after the incident, the miscreant fled towards Julena.
A similar incident occurred a few metres away at the Shaheen Bagh protest site, where an unidentified person hurled a petrol bomb. No one sustained injuries in the incident.
