The four-foot-long reptile was spotted in a park by passers-by, who immediately called 911.
Police and park rangers raced to catch the 'gator, and eventually managed to get a rope around its neck.
Living in the pond?
Luckily, no one was hurt while the alligator was walking around on its own.
Police said they didn't know if the reptile was an escaped pet, or had been living in a pond in the park for some time.
It's now been taken to a reptile specialist, who's used to looking after alligators.
