Seven arrested for allegedly posting, phoning in threats to NYPD

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.
