An attack on passengers inside a San Francisco International Airport terminal on Friday left three with cuts and scrapes before the suspect was arrested, authorities said.
The attacker tried to injure travellers at around 6 pm in the pre-security public area of the International Terminal, airport officials said.

The passengers were treated for minor injuries before continuing on their travels and other airport operations weren't affected, officials said.
It wasn't clear if the suspect was a traveller and the motive for the attack was unknown, airport duty manager Russell Mackey told the San Francisco Chronicle.
A KTVU-TV reporter who was covering the Golden State Warriors' homecoming at the airport said a large knife was removed from the scene.
Other details weren't immediately available.
