He’s a ‘gator on the lam.

Chicago officials hoping to catch a wayward alligator dubbed “Chance the Snapper” have shut down a lagoon and neighboring roads after a fruitless week-long search for the croc.

Animal control have been searching for Chance since he was first sighted at the Humbolt Park Lagoon on July 9 — with animal control speculating the 5-foot gator was most likely abandoned by its owner after becoming too big.

Local wrangler “Alligator Bob” has toiled in a canoe for the last six days setting traps in the lagoon but Chance has evaded capture, frustrating officials who on Sunday announced they were bringing in an expert from Florida and shutting down half the park, the Chicago Sun-Times reported.

The bandit had become a local minor celebrity, spawning at least one parody Twitter account and drawing energetic gator watching parties of more than 100 admirers.

On Monday, Chicago Animal Care and Control said the masses of visitors participating in “Gator Watch 2019” were spooking Chance and keeping him underwater.

“We are taking these steps to in an attempt to create an environment that lends to the animal’s safe capture so we can quickly reopen the entire park to activity,” spokeswoman Jenny Schlueter told ABC News.

Neighborhood website Block Club Chicago has begun selling gator watch wear while the Chicago Tribune declared “The Humboldt Park alligator is all the rage.”

Gallingly, The Cut suggested Chance was a rival to Central Park’s hot Mandarin duck.

A public competition led to the outlaw to be named after Chicago musician Chance the Rapper — beating out other suggestions “Ruth Gator Ginsburg,” “Croc Obama” and “Frank Lloyd Bite.”

Alligator Bob was not impressed, telling the Sun-Times on Friday, “All these people are not helping.”

“It sounds great to be having alligator naming contests. They’re selling T-shirts up there right now and handbooks. It’s like, really?” he said.

Mayor Lori Lightfoot has ordered the City of Chicago bring in expert Frank Robb, who owns Crocodilian Specialist Services in Florida to assist in the capture.

Robb arrived in Chicago on Sunday and has assessed the park and lagoon — sending Alligator Bob packing.

It’s not clear if Alligator Bob — a carpenter by trade and volunteer with the Chicago Herpetological Society — is still associated with the search efforts but he was seen removing his traps on Sunday.

Closures at Humbolt Park Lagoon will remain in place until authorities are able to bring Chance in.
