The gator was first spotted at Victor Crowell Park last week.
Police body camera footage shows the moment officers moved in on the four-foot-long gator on Thursday night.
The officer was able to put a leash around the alligator's neck before putting it into his patrol car.
As of Friday night, the gator is in the care of the Cape May County Zoo.
It will eventually be moved to a sanctuary in Tampa, Florida, according to officials.
