Joseph Williams, 41, allegedly threw a box and four weights at the victim in the building on Patchen Place near Greene Avenue at 7:46 a.m. Tuesday.

“What are you gonna do now!” he screamed before pulling a knife and chasing the victim, then hurling yet another weight at him, the sources said.

Even as the target of his venom dialed 911, Williams allegedly continued to curse at him — and soon found himself under arrest on charges of assault, weapon possession, menacing and harassment.

At about 10 p.m. last Saturday, Davon Williams, 21, ordered four pies from a pizzeria, then waited outside 1267 Lincoln Ave., the sources said.

When the deliveryman arrived, two of Williams’ pals allegedly grabbed him and put a gun to his back.

Manhattan

A woman was allegedly twice sexually assaulted in a Midtown karaoke bar, according to police sources.

The 22-year-old victim said she met her first attacker in a nightclub at about 3 a.m. Tuesday and they later hopped in a cab and headed to the bar on 32nd Street near Fifth Avenue.

But the creep started kissing her as they rode an elevator to the lounge, she said, and when she rejected his advances, he pinned her against a wall and sexually assaulted her.

Afterward, she told investigators, she walked to the bar — and one of the suspect’s pals forced her into a room and raped her.

Both men fled and the woman reported the incident to the police. She was taken to Bellevue Hospital, where a rape kit was administered.
