Coming Soon Again in New York. The graphic image surfaced Monday on a few jihadist websites, featuring the words in the English, and has prompted officials to investigate who posted it. FBI spokesman J. Peter Donald said that while his agency was investigating, "there is no specific or credible threat to New York at this time." "The NYPD Intelligence Division's cyber unit is investigating the origin and significance of the graphic," said NYPD spokesman Paul Browne. Until more is learned about their origin, we take all threats against New York City seriously. The posting comes just months of the 10 year anniversary of the 2001 terrorist attacks in New York, Pennsylvania and Washington.
