A man was robbed at gunpoint by three goons in South of Market on Monday, police said.

The 29-year-old victim was walking in the 100 block of San Bruno Avenue about 10:30 p.m. when three people drove up to him in a green Ford Expedition, police Officer Carlos Manfredi said.

One suspect brandished a gun and demanded the victim’s belongings, police said. The victim turned over his cellphone, cash and watch and the trio fled in the SUV.

Later, police impounded a vehicle that matched the description of the suspects’ SUV, Manfredi said.

The suspects are still at large, Manfredi said.

The armed suspect who demanded the victim’s property was described as 6-feet tall and 220 pounds, wearing a green sweatshirt and blue jeans. The other two suspects were described as being between 5-foot-8 and 5-foot-10 and between 140 to 150 pounds. No further descriptions were available.
