First Squad detectives are looking for four men -- armed with a gun and a knife -- who stole an iPhone and a set of keys Wednesday from a 15-year-old boy in Baldwin, Nassau County police said.

The four men, in a blue sport utility vehicle, pulled up to the youth as he walked west on Eastern Boulevard about 8:15 p.m., police said in a Thursday news release.

Three of the men pulled the youth into the vehicle. One had a handgun, another a knife, and a third held the victim down in the rear cargo area, choking him, police said.

The fourth man, the driver, went around the block and then the victim was released, police said.

Police also said the victim declined medical attention at the scene.

Police said the vehicle was a light-blue, square-shaped SUV.

Anyone with information can call Crime Stoppers, 800-244-8477. All calls will be kept confidential.
