CHICAGO (NBC) - The alligator in Chicago's Humboldt Park Lagoon was captured overnight into Tuesday morning after a weeklong search mission that drew national attention.
Chicago officials and wildlife experts caught the alligator in the overnight hours, police said early Tuesday, one full week after it was first spotted swimming in the lagoon.
The gator was first seen the morning of July 9. Photographer Rencie Horst-Ruiz told NBC 5 she was at the lagoon around 6:30 a.m. when she saw the alligator and snapped photos. She reported the creature appeared about 4 or 5 feet long.
Illinois Conservation Police and Animal Care and Control responded to the scene hours later to investigate.
Animal Control then brought in a reptile specialist dubbed "Gator Bob" who took over the effort to place live humane traps that night. The creature continued to evade capture for days, at which point city officials decided to take a new approach.
The east side of the lagoon was fenced off from the public entirely on Sunday night and an expert from Florida was brought in to try his hand at the hunt.
The CACC hired Frank Robb, an alligator expert who owns Crocodilian Specialist Services in Florida. Robb was recommended by local experts in Florida, and arrived in Chicago Sunday for an examination of the area surrounding the lagoon.
No traps remained in the water as of Monday evening, according to Chicago Animal Care and Control Executive Director Kelley Gandurski, who said Robb was instead focused on tracking the animal, which was last officially spotted early Thursday morning.
Officials warned that crowds gathering at the lagoon may have "altered" the animal's behavior.
"He was hiding," Grandurski said, noting the closures were put in place to capture the animal and not out of concern for the public.
