HONOLULU -- City officials said the Honolulu Zoo is making immediate changes after a tiger escaped from a newly-built exhibit on Thursday.

No one was injured during the animal's moments of freedom. However, it was long enough to cause a scare and require a thorough review of safety protocol.

The pending changes at the zoo are both in operations and physical changes.

Zoo officials on Friday showed KITV where and how Berani, the 8-year-old Sumatran tiger, got out.

"The animal exited through here and then he traversed into that holding area and right in through there," city Enterprise Services Director Sidney Quintal said. "As soon as that occurred, the volunteer who was cleaning in the area exited the holding area secured there."

Zoo officials said for less than 5 minutes, Berani was in an open area of the zoo.

"We're still, again, like I say, trying to piece together what happened between that gate and this gate, and how did they come to be open," Quintal said.

The zoo will add springs to the holding doors to keep them closed, officials said.

"And we're also going to add an additional fence enclosure. It's going to come out about 12-15 feet, and we're going to close it back up to that corner," Quintal said.

Zoo officials said they hope to start taking bids for construction on the extended enclosure within the next couple of weeks.

Volunteers at the tiger exhibit are being put on hold until a complete review of the incident is completed, he said.

The zookeeper and the female volunteer are both receiving employee assistance for the trauma they experienced on Thursday, officials said. The zookeeper, who has 10 years of experience, did report to work on Friday.

A national representative from the People for the Ethical Treatment of Animals said the Honolulu Zoo has put the community in a serious safety risk and has requested the U.S. Department of Agriculture to investigate the escape.

"It would seem after the tragedy on Christmas Day at the San Francisco Zoo, where a tiger escaped and killed someone, and ended up being shot and killed herself that every zoo in the country would be extra vigilant about their safety procedures," the representative said.

Those who stopped by the tiger exhibit on Friday said they don't feel the tigers and their exhibit are a danger.

"I think the enclosure is completely safe, as long as everything is locked," Minnesota visitor Sharon Barber said.
