One of the men then stabbed him in the leg.
A police spokesman said: “The suspects are described as two black males, both wearing black or dark clothing from head to toe with one of them wearing a mask.
“The other had the hood on his hooded top down.”
The spokesman added that the teenager’s injuries are not life-threatening.
