Police are seeking a teenaged suspect in the stabbing of a 76-year-old man in the Portola district yesterday afternoon.

The incident occurred on the 800 block of Dartmouth Street around 2:56 p.m. when the victim returned to his residence and found the suspect, a 17-year-old male acquaintance, inside his home without permission.

Police said it's unclear how the suspect gained entry, but "a verbal altercation ensued" that escalated to a stabbing. After the attack, the suspect fled on foot, and the victim was taken to a hospital with non-life-threatening injuries.

Anyone who has information about this incident is encouraged to contact SFPD via the department's anonymous tip line at 415-575-4444, or text TIP411 with "SFPD" at the start of the message.
