In the latest of such incidents at Prospect Park Lake in Brooklyn, New York, a mysterious stranger released exotic wildlife there, then walked away.
According to HuffPost, a witness said he saw a man dragging two large bags to the shoreline, of what appeared to be wriggling snakes.
The man dumped bags of live eels into the water.
Officials identified them as swamp eels native to Southeast Asia, which have been found in at least eight states.
