On Friday evening a 29-year-old man had his neck allegedly slashed with a machete near the UN Plaza entrance to Civic Center BART station closest to Seventh Street, and the suspect remains on the loose. Initial reports had it that the assailant was around 25 years old, and had attacked the victim with a "big knife," as KRON 4 reports, possibly with as big as a two-foot blade. The suspect was last seen fleeing the area, and the victim was transported to the hospital with unknown injuries.

As Hoodline reported, one Twitter user posted a video of the victim lying facedown in the station with blood smears visible on the ground as two people rushed to his aid.

The incident happened around 8:39 p.m. Friday, and both the SFPD and BART Police are investigating according to SFPD spokesperson Officer Giselle Talkoff. It remains unclear whether the attack too place inside or outside the station, though it appears the victim collapsed inside the station near the ticket machines.

The Chronicle reports that the assailant may also be a man in his 40s.

No further descriptions of the victim or the assailant have been given.

This attack follows on another in mid-December at a different entrance to Civic Center Station in which a young man was pushed down a flight of stairs and stabbed.
