TUPELO, Miss. – Oliver apparently has learned to pick locks, making his second breakout from behind bars in less than a month.

On Wednesday, however, the white-faced capuchin monkey was back at the Tupelo Buffalo Park and Zoo, and this time his cage has been secured with triple chains and locks.

“There’s one on top, one on the bottom and one in the middle,” park manager Kirk Nemecheck said. “If he gets out again, someone is letting him out.”

Oliver’s cage was standing open Monday morning and the lock was lying on the ground. Oliver and another capuchin named Baby were still in the area, and workers easily recaptured Baby, but Oliver took off, Nemecheck said.

The 9-year-old primate was found Tuesday in a yard about four miles from the park.

“The police showed up and helped us,” Nemecheck said. “We surrounded him, a guy jumped on him and got his hand bit, but we got him.”

The capuchin, a species of monkey native to South and Central America, also freed himself July 31 and wasn’t apprehended until Aug. 6.

This is Oliver’s third escape. His first was about six years ago.

Nemecheck is getting fed up.

“I’m getting titanium locks next time,” he said. “I’m tired of chasing a monkey.”
