Westminster police say the attacks appeared to be the result of a fight, which may have been gang related and involved as many as 12 individuals.
Investigators say those involved in the fight had left the area prior to officers arriving, but later officers were summoned to a local hospital where one of the apparent victims from the fight had been dropped off by friends.
A second victim had wandered into a neighboring Fountain Valley residential area where he summoned help from a resident, who then called the Fountain Valley Police Department. Both victims sustained stab wounds but are expected to survive.
Investigators are now trying to find eyewitnesses to the attacks.
