A 27-year-old man armed with two handguns approached a police officer in Wisconsin, but the incident ended peacefully, largely because an NYPD officer had alerted Wisconsin officers that the man had threatened violence against them online that day, reports the New York Daily News.
NYPD Officer Gregory Santora tipped off Madison, WI, police of an impending attack on law enforcement there after he happened across a video of Raynarldo Glenn live-streaming on the app Periscope Saturday morning
Santora was off-duty and at home when he chanced upon the video. "While I was watching it he was saying and implying that he was going to live-stream the shooting of the police officers," Santora told the New York Daily News. "That's what really got me scared."
Santora said he was spurred to action because he is haunted by the 2014 assassinations of Officers Rafael Ramos and Wenjian Liu in Brooklyn.
"I didn't want to see that happen in the city of Madison," Santora said. "I wanted to see this individual be taken into custody without any violence."
