I say that is a muskrat, not a coypu (nutria), the tail is long and hairless. Also coypu have a white muzzle. Muskrat tails are kinda like beavers, because they are flattened, but vertically rather than horizontally. Can't really tell on this photo, but looks like a muskrat to me. They are wild animals, nobody had to release em. Very very common (or used to be) where I come from in Indiana.
Looks like a muskrat to me, too.
