Delhi Police — lack of police patrolling in university of delhi north campus

This is in regard with lack of police patrolling in university of delhi north campus area. It was day before yesterday i. E 30th september 2018 that two men on motorbike tried to snatch my phone from my hand while i was on my way to college at 10:30a. M in an e-rickshaw. The area of incident was kirori mal college. I shouted and scratched the culprit's hand and was alert enough to not let my phone go but it might have gotten stollen and nobody would've been there to prevent this act. They rode the bike too fast to let anyone note their vehicle no. And so wasn't able to chase them down. I would urge the police department to kindly increase the patrolling in the above mentioned area. Thank and regards.
