Brawls led to stabbings in a San Francisco alley and nightclub Sunday, police said.
A 42-year-old woman and 55-year-old man survived the unrelated knife attacks.
Around 6 a.m., the 42-year-old victim was stabbed on the left side of her chest following a spat in an alley at Shannon and Geary streets, police said.
The woman was rushed to San Francisco General Hospital after the fight. The stabbing suspect, a woman in her early 40s, fled and has eluded arrest, police said.
Around 7:45 p.m. Sunday, a 55-year-old man who attempted to break up a fight in popular Dogpatch-area nightclub Café Cocomo was stabbed in the arm, police said. The man was transported to SFGH with a minor injury, police said.
The club at 650 Indiana St. has seen its share of violence in the past. In October last year, a man suffered life-threatening injuries in a shooting inside the establishment.
The incident was one of several examples of nightclub violence in The City that spawned calls from city officials for rigid security measures.
