It seems no one is safe on the streets of the Big Apple these days – not even beloved hometown actor and Brooklyn native Steve Buscemi. Buscemi, 66, was strolling through Kips Bay last week when a brute walked up and struck the “Boardwalk Empire” star in a broad-daylight attack – one of the latest unprovoked assaults in the five boroughs, law enforcement sources told The Post. The actor suffered swelling to his face and left eye and was taken to Bellevue Hospital for treatment. Meanwhile, his deranged assailant took off and is still on the lam, police sources said.
