NEW YORK (CBSNewYork) -- The NYPD is investigating several threats to kill police officers on New Year's Eve.
A new batch of threats has been posted on social media warning the NYPD, WCBS 880's Monica Miller reported. Several alleged gang members are also using hashtags that include "#2deadcopseveryday" and "#wingsonpigs."
The threats come 11 days after NYPD Officers Rafael Ramos and Wenjian Liu were ambushed in their patrol car in Bedford-Stuyvesant, Brooklyn. Before the deadly shootings, the gunman, Ismaaiyl Brinsley, who also killed himself, posted on Instagram: "I'm putting wings on pigs today. They take 1 of ours, let's take 2 of theirs." He cited the police-involved deaths of Eric Garner on Staten Island and Michael Brown in Ferguson, Missouri.
