A man was arrested and charged with attempted murder after a fight in the Tenderloin on Friday led to a stabbing that critically injured another man, police Officer Albie Esparza said Monday.
Ernesto Tun-Catzin, 32, of San Francisco was with a group of people in the 200 block of Leavenworth Street about 2 a.m. when he reportedly challenged a 19-year-old man to a fight, Esparza said.
The 19-year-old had been walking down the street with a friend. The victim and suspect did not know each other, Esparza said. Witnesses told police the two engaged in a physical altercation that ended when Tun-Catzin stabbed the 19-year-old several times in the torso and back.
The victim was taken to a hospital with life-threatening injuries, Esparza said. The victim’s friend, a 24-year-old man, also was assaulted, but his injuries were minor.
Responding officers canvassed the area and found Tun-Catzin among a group of people in the 200 block of Turk Street, Esparza said. Tun-Catzin and the others matched descriptions given to police by witnesses.
Three of the men were detained, but only Tun-Catzin was arrested, Esparza said. He was booked on charges of attempted murder and battery with serious injuries.
The investigation is ongoing and anyone with further information is encouraged to contact police at (415) 575-4444 or by text to TIP411.
