A 39-year-old man was critically wounded after being stabbed by two suspects who tried to use a portable toilet in his parking lot in San Francisco’s Tenderloin, police said.

The victim, who was not identified, denied a man and woman from using the toilet in the parking lot at Eddy and Taylor streets around 1:30 p.m. Sunday. Rather than moving on, the couple attacked the man, stabbing him multiple time in the torso, police said.

The couple fled the scene. No suspects were immediately identified or arrested in the stabbing. The victim was rushed to a hospital with life-threatening injuries, police said.
