May be not as bad as 1st thought:
The NYPD addressed the viral video on its official Twitter "news" account.
"In regard to a video on social media that took place at 2 Ave & 25 St, a woman taken into custody in an unmarked van was wanted for damaging police cameras during 5 separate criminal incidents in & around City Hall Park. The arresting officers were assaulted with rocks & bottles," the NYPD said. "When officers from the Warrant Squad took the woman into custody in a gray NYPD minivan this evening, they were assaulted with rocks and bottles. The Warrant Squad uses unmarked vehicles to effectively locate wanted suspects."
Didn't see too many rocks or bottles flying around in the video though.
