Here's the deal ... cops captured the misplaced marsupial Thursday after getting tons of calls about the wild animal roaming some neighborhood streets. Yes, even in Florida, that's a strange sight.

As you can see, the kangaroo, whose name is naturally, Jack ... ended up behind bars in a stall at the Mounted Police headquarters, a barn normally reserved for equine officers.

It took a lot of manpower to get Jack in custody ... several police units were needed to surround and pen in the marsupial, who was eventually introduced to the back of a squad car.

Jack's owner, Anthony Macias, says the animal is 2 years old and means no harm.

Police say Jack won't be returned to Anthony because Fort Lauderdale is not zoned for kangaroos ... instead, Jack is being turned over to the South Florida Wildlife Center.
