The suspect drove to the airport around 6 p.m. local time and walked around the departure terminal before drawing the gun and assaulting three men, San Francisco Police Department spokesman Robert Rueca said in a statement.
The victims were treated for non-life-threatening injuries at the scene and released, Rueca said.
The suspect’s identity is being withheld at this time, pending charges and an active investigation, Rueca added.
Police urge people to come forward and contact the department if they have any information about the assault.
