The family of a 3-year-old boy who fell into an animal enclosure, prompting the killing of an endangered gorilla, said on Wednesday that it would not sue the Cincinnati Zoo over the incident.

The family, whose name has been withheld by police, said through a spokeswoman, Gail Myers, that the boy was doing well. They had said earlier on social media that he had a concussion and scrapes. They asked well-wishers not to send them financial gifts, but to make any donations to the zoo.

A 17-year-old western lowland silverback gorilla named Harambe was shot and killed by zoo staffers on Saturday after the boy fell into its enclosure.
