Police Commissioner James O'Neill says there's been a 31 percent rise in hate crimes this year.
O'Neill says there have been 25 hate crimes against Muslims this year, up from 12 in 2015.
There has also been a slight uptick in anti-Semitic crimes, from 102 to 111.
The commissioner issued a warning to anyone who commits such a crime.
"There's been a lot of rhetoric, but this is New York City, and we're much better than that, and we won't tolerate these crimes. We have the best hate crime investigators in the United States of America. So if you're going to engage in behavior like this, make, rest assured that you'll be arrested as quickly as possible and we'll work with our prosecutors to make sure that you're fully prosecuted under the hate crimes statutes," O'Neill said.
Since the election, there have been a couple of incidents being investigated as hate crimes, including swastikas found on the door of four dorm rooms at the New School.
