This morning at around 8:30am, a passenger on the N-Judah streetcar pulled a knife and threatened other passengers during the rush-hour commute.

According to tipster Sunny W., a man boarded at the 7th Ave. and Irving stop and began screaming obscenities.

Tensions escalated after he pulled a "long knife" out of his backpack and started threatening passengers. Another witness described it as a "chef's knife."

"Many passenger[s] freaked out," said Sunny, who said he was about ten feet away in a window seat. "Many of us started to move towards the front of the train (this took place in the back of the first train)."

The man got off at the next stop, at 4th and Irving. One witness on Twitter, jflip3693, reported that he was heading towards UCSF.

No one was injured in the incident.

"This could've ended really badly given how packed the train was at the time," said Sunny. "I saw him at the train stop before boarding and he was already talking to himself and was visibly upset about something."

jflip3693 also gave SFMTA a detailed description of the suspect.
