The news source said a Mexican Army officer told them the suspects are being detained in the city of Agua Prieta, Mexico, a few miles away from where Ivie, 30, was shot to death.
ABC15 is working to confirm the information.
Ivie was killed after he and two other agents responded to a sensor hit a few miles north of the Arizona-Mexico border just before 2 a.m. Tuesday, seven miles east of Bisbee.
The two other agents involved included one who was shot in the buttocks and ankle, but is expected to be OK.
