Two men who brawled early Thursday morning in Duboce Triangle used a knife and a glass in their scuffle before police arrived on the scene.
The 2:23 a.m. fight near Noe and Henry streets was started by one of two 50-year-old men, said police, who did not give further details on the cause of the incident.
At some point after the fight began the victim jumped on the suspect and hit him with glass. The suspect’s response was to begin stabbing the other man with a knife.
When police arrived they arrested the suspect and the victim was taken to a nearby hospital for treatment.
