Cohen says New York City and its large Jewish population face constant threats in al-Qaida, the Hezbollah guerrilla group and so-called homegrown terrorists. But he stresses that the department has no evidence of any specific terrorist activity related to Passover.
Police officials say that as a precaution, the NYPD will step up patrols in Jewish communities and around places of worship.
The weeklong Passover observance begins at sundown on April 19.
