From [HERE] and [MORE] A New York police detective shot and killed an unarmed man, whose hands, a witness said, were on the steering wheel of his Honda, after he had been pulled over early Thursday for cutting off two police trucks on the Grand Central Parkway in Queens, the authorities said.

The detective, Hassan Hamdy, 39, a 14-year veteran assigned to the Emergency Service Unit, fired one bullet through an open window of the car, which his squad had just pulled over with the help of a second police vehicle. The bullet struck the driver, Noel Polanco, 22, in the abdomen. He was declared dead less than an hour later at New York Hospital Queens.

A passenger in Mr. Polanco’s car, Diane Deferrari, said in a phone interview Thursday night that just before pulling the car over, officers appeared irate that Mr. Polanco had cut them off. She said that one of the officers — but not Detective Hamdy — stuck up his middle finger and was screaming obscenities from one of the moving police trucks.

“As soon as we stopped — they were rushing the car,” Ms. Deferrari said. “It was like an army.”

She said a group of officers swarmed the car, yelling for the three people in Mr. Polanco’s car to put their hands up. Mr. Polanco, whose hands were still on the steering wheel, had no time to comply, Ms. Deferrari said. At that instant, a shot rang out, and Mr. Polanco gasped for air, she said.
