San Francisco police are seeking suspects in two recent stabbings, they confirmed today. In one, a man was critically injured by an angry mob, and in the other a person was slashed in the face just steps from the tony Westfield San Francisco Centre.

According to SFPD spokesperson Officer Grace Gatpandan, a 26-year-old man was seriously injured in a stabbing at 1:30 a.m. Saturday.

Police say that the victim was arguing with another man on Albion Street, near the bustling intersection of 16th and Valencia Streets. Attempting to end the argument, the victim turned away, but the man with whom he'd been arguing and four others (all, reportedly, aged between 25 and 30) physically attacked him.

During the attack, one of the members of the mob stabbed the victim in the "upper back," Gatpandan says, seriously injuring him. He was transported to San Francisco General Hospital, and returned home to recover on Monday, Mission Local reports.

All the suspects fled, and remain at large at publication time.

Then, at 2 a.m. today, a person was stabbed in the face at Fifth and Market Streets, which is near the Powell Street Cable Car turnaround.

According to KRON4, "detectives are gathering forensic evidence and canvassing for witnesses in the area," but did not have any information on the victim or any suspects, other than to say that the injured party was transported to SF General for treatment.

Anyone who witnessed either the stabbing or has any information about either case is urged to contact SFPD at (415) 575-4444 or to text an anonymous tip to 847411 with “SFPD," then the message
