A child was injured after crawling under a fence and sticking his hand into a wolf enclosure at the ZooAmerica North American Wildlife Park in Pennsylvania, the zoo said.
The incident occurred on Saturday, April 4, a spokesperson for Hershey Entertainment and Resorts Company confirmed to USA TODAY. The unsupervised 18-month-old crawled under an exterior perimeter fence and headed to the primary metal enclosure of the wolf habitat, where the child put his hand through the fence, according to the spokesperson.
"A wolf approached and made contact with the child's hand," the zoo added. "This type of response is consistent with natural animal behavior, and was not a sign of aggression."
