Cleopatra's Needle

A naked man has been seen near the Needle - he jumps into the water but no splash is heard, and the sounds of laughter or agony laden groaning have been heard too. Another figure has been seen standing on the wall, but when anyone approaches him, he jumps - but again, no splash is heard. Yet another version is that police are approached by a lady nearby begging with them to avert a suicide. When they get there, the same lady is seen plunging into the water. And once more, no splash is heard.
