Three Marines were transported to a hospital after being stabbed during an altercation in San Clemente early Saturday, officials said.
Authorities received a call just after 1 a.m. about three people involved in a fight in a parking lot between Avenida Granada and Avenida Victoria, Orange County Sheriff's Department spokeswoman Jaimee Blashaw said.
The agency initially said that the Marines were trying to break up a fight, but a spokesperson later told KTLA that they were involved in a confrontation against two men and a woman.
One of the men stabbed all three Marines, a 23-year-old and two 21-year-olds, who were taken to the hospital with injuries that were not life threatening, the Sheriff's Department said.
The assailant was later identified by the O.C. Sheriff's Department as Alexis Moreno-Aguirre, 24, and he was arrested on suspicion of attempted murder.
Moreno-Aguirre and his two friends were at a hospital, where they were detained, officials said. Earlier, authorities said the perpetrators were on the loose.
The incident happened near a bar, where witness Eric Clavelle said the scene could get rowdy.
Officials provided no further information.
