Three people were stabbed in separate attacks in The City on Tuesday, including a 15-year-old boy on a Muni bus, police said.
The Muni stabbing happened after a verbal spat between teenage passengers in the area of Bayshore Boulevard and Cortland Avenue around 6:40 p.m., police said. The 15-year-old was sliced on the side of the head after arguing with two other teens, ages 19 and 16, police said.
The 19-year-old, described only as a Hispanic man, is the stabbing suspect, police said.
Earlier Tuesday, a 37-year-old man was stabbed in his arm during an attempted robbery in the 200 block of Leavenworth Street, police said.
The thug, a black man standing 6-feet tall and weighing 180 pounds, crept up behind the victim around 8 a.m. and tried to snatch cash from his hand. A brawl ensued. The crook pulled out a knife and stabbed the victim in the arm three times, cops said.
The victim refused medical attention, police said.
About an hour before that attack, a 26-year-old man walking to work was stabbed multiple times by a punk with a 6-inch knife, police said.
The suspect was in a vehicle that was trailing the victim slowly, police said. At 21st and Folsom streets, two thugs got out of the car, yelled at the victim, and while one began slashing him with the knife the other kicked him, police said.
The victim suffered lacerations to both forearms and his right upper thigh. He is reportedly in stable condition, police said.
The suspects, described as Hispanic men, fled in a black, older-model 4-door American car, police said.
The stabbing suspect is 28 years old, standing 5-feet, 6-inches tall, and carrying a 6-inch folding knife, police said. A second suspect is 25 years old, standing 5-foot-4. A third suspect, who had an 8-inch knife, was described only as being 24 years old, police said.
There have been no arrests in all three stabbing cases, police said.
