While they have managed to keep most of the heinous crimes under control, violent clashes and protests have kept the Delhi police on its toes.
In past few months, Delhi police have faced several protests and clashes such as the ones at the disputed Akbarabadi mosque site, Arvind Kejriwal's protest and most recently the riot at Mayur Vihar phase III.
Police said 40 cases of riots have been registered so far as compared to 34 last year during the same period.
"In most of the cases, we were forced to register cases of riots as protesters vandalised public property," said a senior police officer.
Police said that number of protests rose ever since the city witnessed two of the biggest protests - Anna Hazare's anti-corruption movement and Ramdev's campaign against black money.
But this year, for senior police officers it was the protest at the disputed Mughal-era Akbarabadi mosque site that is keeping them busy.
In fact, protests and demonstrations have gone up in the city. In 2010, Delhi police had to make arrangements for 3,093 demonstrations, rallies or protest while the number jumped to 7,864 in 2011.
