The four men got out of a dark, four-door sedan around 10:45 p.m. on Hempstead Gardens Drive and approached two 18-year-old men, asking them the time, police said. Then the four asked for money and began punching them.
Police said one of the four pulled out a small silver handgun and another went through the victims' pockets. After coming up with a cell phone but no money, police said the men fled in the sedan, driving east on Washington Avenue.
The two victims declined medical attention, police said.
