In the first incident, shots were fired into an inhabited home on the 1200 block of Revere Street in the Bayview District Monday morning.
According to police, the suspects pulled up to a home in a dark green four-door vehicle and fired one shot from the vehicle toward the residence at 11:53 a.m.
One suspect sitting in the backseat got out of the car and fired several more shots at the home, police reported. The suspect then got back into the car and the suspects fled. No one was struck by the gunfire.
The second incident was a robbery and shooting reported at 3:08 a.m. in the city's Tenderloin District at Hyde and Turk streets.
Five suspects in a green four-door Ford with tinted windows got out of the vehicle and went up to various people, brandishing guns and demanding money, police said. One victim was a 38-year-old woman. A suspect approached the woman with a gun and took her wallet and cash.
Police do not know if the suspects were successful at other robbery attempts. Another suspect began to fire shots before all five of the suspects returned to the vehicle and fled.
The suspects are described as men between the ages of 18 and 25.
No arrests have been made in either incident.
