Authorities say no decision has been made yet on whether to bring charges against of the parents of a 3-year-old boy who fell into a gorilla enclosure at the Cincinnati Zoo, causing an animal response team to fatally shoot the primate.

Cincinnati city spokesman Rocky Merz said Wednesday no determination has been made on possible charges nor has anything related to the case been released by departments investigating the incident.

Meanwhile, in a 911 call released Wednesday, the boy's mother pleads for help while shouting at the child: "Be calm!"

Another woman is heard telling bystanders at the zoo Saturday to be quiet because they're annoying the gorilla.

The boy's family released a statement saying he continues to do well and expressing gratitude to the Cincinnati Zoo for protecting him.
