NYPD urges vigilance after Philadelphia shooting

The New York Police Department is urging officers to be extra vigilant after attacks on police in Philadelphia and Paris.

The internal memo Friday, obtained by The Associated Press, was titled “officer safety alert” and warned police to take proactive safety measures.

A knife-wielding suspect lunged at officers in Paris on Thursday before being shot. Shortly before midnight in Philadelphia, a gunman opened fire on an officer in a patrol car, wounding him. Philadelphia police officials said Friday the suspect used a stolen gun and told investigators he was an Islamic State supporter who acted in the name of Islam.

The NYPD memo says the two incidents “demonstrate the continued threat that members of service face from individuals seeking to target law enforcement personnel for a variety of reasons, including terrorist motivations.”
