Brandon’s grandmother was watching him while his mother was at work when he was kidnapped, police had said.
The grandmother took the child inside her apartment and went back outside for a short time to unload groceries, police said. While the baby was alone, a man entered the apartment and took the child, they said.
Police released surveillance video showing a man walking on a sidewalk with a covered car seat, which investigators said held the child.
Police did not immediately say if any of the suspects in custody was the same person in those images.
The suspect previously described by police appeared to be a stranger, and neither the baby’s grandmother nor mother recognized the man, Sgt. Christian Camarillo said Monday, before Brandon was located. The child’s father is incarcerated, he said.
“Anybody who is a mother or father, you don’t love anything more than you love your child,” Camarillo said.
