A Chinatown-area robbery team employed a new and disconcerting weapon in their effort to separate people from their stuff: Piss.

According to the San Francisco Police Department, a 27-year-old man was walking near the intersection of Stockton and Sacramento Streets at 3:30 a.m. Sunday when the unpleasant attack occurred.

Two men of "unknown ages," police say, approached the victim, "threw urine in [his] face and hit him with an unknown object."

After what police characterize as "a brief struggle," the pee pitchers made off with the man's cash, wallet, credit cards, and headphones.

The victim, who suffered minor injuries in the attack walked to a nearby hospital for treatment and to report the crime.

The suspects fled, and haven't been seen since. According to the SFPD, no arrests have been made, but anyone with information on the urine assailants should call SFPD's Anonymous Tip Line at 415-575-4444 or to text a tip to TIP411 with SFPD at the beginning of the message.
