A stabbing last night at a popular tourist destination has left one man in critical condition. The Chronicle reports that this all went down at the intersection of Mission Street and Clarion Alley — a block whose rotating murals have made it a favorite of tourists and locals alike.

The attack is reported to have occurred at 8:50 p.m. and was witnessed by one person. Police told the paper that the victim is in his early twenties, and that the assailant fled the scene after the stabbing.

At this point there are no details as to any possible motive, and no arrest has been made.

This is not the first stabbing to take place in or near Clarion Alley. This past April the Chronicle reported that a 29-year-old man on the same block was stabbed in the stomach when a group of four men apparently tried to rob him.
