A pair on gun-wielding robbers terrified two visitors to a San Francisco tourist attraction Tuesday, creeping up on their victims as they took photos at the popular venue.

According to the San Francisco Police Department, the shakedown happened at 10:30 p.m. Tuesday, at the base of SF's iconic Coit Tower.

Police say that the victims, a 42-year-old man and a 52-year-old woman "were at Coit tower taking photos" when the male suspects approached them from behind.

One of the suspects, police say, then pointed a gun at the couple. The victims were so frightened by the threat that they ran from the scene, leaving their belongings behind.

The thieves got away with the couple's camera equipment and tripod, police say, then fled by car.

No further details on the suspects were available at publication time, but the SFPD could confirm that the duo remain at large and no arrests have been made in the case.
