A hang-out time between acquaintances turned horrific Saturday afternoon, when an argument escalated into an attack with an axe.

According to the San Francisco Police Department, at 3:19 p.m. Saturday, five men aged between 25-35 were "hanging out" on the 2300 block of Powell Street, which is between Bay and North Point Streets.

Police say that "a heated verbal argument ensued." A 30-year-old member of the party "then revealed an axe" and struck a 27-year-old member of the group "in [the] abdomen area, causing a deep cut."

The uninjured four men then fled the scene "in a vehicle," police say.

The victim was transported to San Francisco General Hospital for treatment of his injuries, police say. An update on his condition was not available at publication time, nor was additional information on the suspects or the reason behind the attack.

Police did confirm, however that no arrests had been made in the case. If you know anything about this attack, the SFPD asks that you call SFPD's Anonymous Tip Line at 415-575-4444 or text a tip to TIP411 with SFPD at the beginning of the message.
