Following the altercation, the lifeguard tells fellow lifeguards that the suspects flicked a cigarette at his tower.
"You sexually harassed me," the woman yells before attacking the lifeguard again.
The lifeguard was transported to a local hospital with minor injuries. He may have suffered a broken hand, according to L.A. County Lifeguards Capt. Ken Haskett.
"It is a felony to assault an ocean lifeguard, who is a peace officer," Haskett said.
One suspect, who was knocked unconscious, was transported to a local hospital in unknown condition.
Further details on what prompted the attack were not immediately released, but the incident remains under investigation by the Los Angeles Police Department.
