The arrest was made shortly after 7 p.m. Thursday at the Chapman Sports Complex located at 11701 Knott Street, according to Sgt. Vince Vaicaro of the Garden Grove Police Department.
The incident occurred as several youth sporting events were underway on the field, Vaicaro said.
The woman was alerted by her son that her husband, identified as Russel Husges, was coming up behind her in the stands allegedly armed with kitchen knives in each of his hands, investigators said.
The intended victim, who was not publicly identified, ran away from Husges and onto the field screaming for help, Vaicaro said. The suspect was then subdued and disarmed by one of the coaches and an off-duty police officer.
