Police are investigating the early morning robbery Friday of two people not long after they got off a Long Island Rail Road train in New Hyde Park.

The two 25-year-old victims, one a man, the other a woman, exited a train shortly before 4 a.m. and walked toward a taxi stand at South 12th Street, Nassau County police said in a news release.

Both were followed by a group of six -- five of them males -- "who began to verbally insult the victims," police said.

The males "began punching the male victim in the head, grabbed his iPhone and threw it onto a nearby rooftop," police said. The lone female attacker punched the female victim in the head, police said.

The six attackers ran away on Millers Lane, got into a black sport utility vehicle, and fled, police said.

Both victims declined medical attention.

Detectives urged anyone with information about the robber to anonymously call Crime Stoppers at 1-800-244-TIPS.
