New York City Police administrators are warning officers about a heightened threat from terrorists and their sympathizers.
The NYPD Counterterrorism Bureau issued a safety advisory pamphlet to officers citing three recent violent incidents involving suspected supporters of the Islamic State of Iraq and the Levant (ISIL) terrorist group. NBC 4 New York obtained a copy of the pamphlet on Saturday.
The pamphlet urges officers to "exercise a high-degree of vigilance and situational awareness."
The recent incidents cited in the pamphlet include the June 2 shooting of Usama Rahim, who brandished a knife against officers in Boston, the June 13 arrest of Munther Omar Saleh, 20, who confronted NYPD officers with a knife, and the June 17 arrest of Fareed Mumuni, 21, who attempted to stab officers as they searched his Staten Island residence.
