The stabbing occurred inside a nightclub in the 1000 block of Folsom Street, police said.
One male reportedly stabbed another male with a knife at around 1 a.m., police said.
I rode by there around 10.30 with J and the boyfriend on our way to Kontrol at The EndUp (about which more later), and there was already a line of B&T/Marina types halfway down the block. Last night was Sense, with two artists from Sense Recordings, and Taj, one of the residents, so I'm guessing it was probably a progessive night.
Update: More details in this article from the Examiner; looks like a fist-fight got out of control. Fun. According to the Examiner, 1015's liquor license is up for renewal in less than a month; given the issues that the ABC board has had with 1015 in the past, you have to wonder how this incident will be regarded.
