The victim, 24, was talking with another person when two men approached. The victim tried to run away, but one of the men tripped him and held him down while the other brandished a gun, said Menlo Park Police Department spokeswoman Nicole Acker.
They took his wallet and keys, police said. The victim suffered cuts to his arms, police said. The men fled on foot.
Police are looking for a mustachioed 20- to 21-year-old Hispanic man about 5 feet 7 inches tall and 150 pounds. At the time of the robbery, he was wearing dark pants and a black hooded sweatshirt with a red beanie over the hood, police said.
The other suspect was described as having the same height and wearing the same type of clothing, but was thin and of unknown race, police said. This suspect had the hood of his sweatshirt drawn tightly to conceal his face, police said.
