Officer Albie Esparza says the cops don't have many details on the incident, as the victim refused to talk to police about it. But here's what we can tell you:
At about 1:24 a.m., police were called to the 700 block of Larkin Street where they found the victim bleeding with stab wounds in his chest. The victim was taken to San Francisco General Hospital where he's being treated for life-threatening injuries, Esparza says.
Police didn't have a motive for the crime, and said that the suspect was only described as a 5-foot-8 Asian male.
