SFPD have opened an investigation on the Muni Humper, now blandly coined "sexual battery suspect" in police speak, who has been plaguing the N Judah line and was originally brought to the public's attention by Muni Diaries. Thanks to one victim named Amanda, whom NBC Bay Area interviewed last night, in addition to several eye witness accounts, police now have a pretty specific description of the perpetrator:

The suspect is described as a Hispanic male, early 20s, 6’, 250 lbs, mustache and goatee with long cornrows on the side of his head down to the collar. He was last seen wearing a black jacket, jeans, and had earrings in both ears.

The suspect has also been described as short, which contradicts the above police description of 6', and squat and wearing t-shirts with cartoon characters on them. Muni Diaries also posted a photo that Amanda snapped of the alleged humper.
