New York (CNN) — Seven men have been arrested in connection with alleged threats made toward police officers since Saturday afternoon, when two NYPD officers were shot in the head from behind while sitting in their patrol car, New York City police said.
Police said in a statement Wednesday that they have assessed hundreds of online postings and calls to 911 and pressed the public to continue to report any suspicious activity.
“All threats against members of the NYPD are taken seriously and are investigated immediately to determine the credibility and origin of the information,” the statement read.
The arrests come as an investigation is underway into Ismaaiyl Brinsley, the 28-year-old who authorities say shot Officers Wenjian Liu and Rafael Ramos in Brooklyn.

Investigators work the scene where two NYPD officers were shot December 20, in the Bedford-Stuyvesant neighborhood of Brooklyn, New York.
The officers were shot and killed ambush-style Saturday afternoon as they sat in their patrol car in Brooklyn, officials said.
The officers — one with two years’ experience, the other with seven years on the job — were normally assigned to downtown Brooklyn but were working a “critical response” detail in an area with higher crime, police said.
The shooter was found dead in a nearby subway station from a self-inflicted gunshot wound, officials said. The shooter, identified as Ismaaiyl Brinsley, arrived in New York from Baltimore, police said.
The shooting occurred near Myrtle and Tompkins avenues in the Bedford-Stuyvesant section of Brooklyn.
Police officers gather near the scene of the shooting. U.S. Attorney General Eric Holder called the attack “an unspeakable act of barbarism.”

Hours earlier, Brinsley apparently posted on his Instagram account: “I’m putting wings on pigs today … they take one of ours, let’s take two of theirs.” Brinsley committed suicide after shooting the officers, according to police.
One of the most recent arrests came on Wednesday after a 26-year-old allegedly posted pictures of weapons on his Facebook page along with threats to kill police officers, the NYPD spokeswoman confirmed. That individual is charged with making terroristic threats.

Also Wednesday, a 41-year-old was arrested on charges of aggravated harassment and making terroristic threats after he allegedly called into the 84th precinct — where Liu and Ramos had been stationed — and, requesting to speak to Ramos, asked whether the bullets had been removed from the dead officer’s head so “he could kill more cops,” police spokeswoman Sophia Mason confirmed.

Also Wednesday, a man was arrested on weapons and drug charges after he was overheard threatening to kill cops while talking on his cell phone inside a bank in Queens, according to the NYPD.
Of the seven arrests, according to police, three stemmed from postings made on social media and two came on misdemeanor charges of false report incident, in which the suspects allegedly called into 911 — reporting threats made by a third party that were later debunked. One arrest was made after the suspect phoned in a direct threat to 911.
