An armed man wearing a mask robbed two people in Golden Gate Park last night.

A 49-year-old man and 31-year-old woman were leaving an event at a museum when a masked man in his 20s approached them on Nancy Pelosi Drive at 11:20pm before firing a shot in the air and demanding their property.

The two gave him their tablets, credit card readers, and money. The suspect then fled the scene in a car. He was last seen heading westbound.

While police did not say reveal which museum event the two had attended, on Thursday evenings, the California Academy of Sciences hosts Nightlife, a themed cocktail party.
