An alligator was making the rounds at O'Hare Airport in Chicago at Terminal 3, leaving passengers startled after spotting the 2-foot-long alligator.
Security guard Tineka Walker, who was on patrol in Terminal 3 at the time, was alerted by a passenger of the alligator at O'Hare airport. No one was left injured by the incident.
"I looked, I said, 'What?' " Walker tells Chicago's WBBM-TV about her reaction when the passenger told her about the alligator.
CBS Chicago reported on Monday that the same alligator was likely captured on a Twitter photo heading to a train at the airport. The animal, which has stunted growth, is now being treated by the Chicago Herpetological Society.
A spokesman for the Chicago Herpetological Society tells the Chicago Tribune that the alligator was still "in distress" Sunday after being found.
"It was in pretty bad shape," Jason Hood, the group's president, tells The Associated Press. "We're trying to get it healthy and find a place for it."
Investigators are still figuring out how the alligator got to O'Hare airport in the first place. WBBM reports "a major clue to how it ended up at the airport emerged on Twitter on Friday when someone posted photos of a man holding what appeared to be the same alligator."
"The patterns on an alligator are as unique as your fingerprints," said Bob Bavirsha, a reptile rescuer with the group, according to CNN. "We can actually match this band right here with that band right there."
