The employee of a San Francisco church is recovering this morning, after police say she was stabbed by a woman who wanted to use the facility's restroom.

According to the San Francisco Police Department, the woman, described by police as a "transient," walked into a church on the 700 block of South Van Ness Avenue, which is between 18th and 19th Streets, at 9:20 p.m. Wednesday.

The Korean Presbyterian Church of San Francisco is located at 720 South Van Ness, and St. Charles Borromeo is located at 713 South Van Ness. An SFPD spokesperson could not confirm to SFist that either church was the location of the incident.

Once inside the place of worship, the woman approached a 39-year-old female church employee and "asked for the bathroom key," police say. When the church's staffer said that she didn't have the key, the restroom-seeker left the church, but as she did so the keyless woman "felt a poke on her buttocks."

Police say that around five minutes later, the church employee realized that she had been stabbed, presumably by the woman who'd just left. The victim took herself to an area hospital for treatment of puncture wounds to her buttocks, and is expected to survive.

Police have not made any arrests as of this morning, nor did they have any additional details on the suspect, a spokesperson says. Anyone with information on the attack is asked to 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.
