The London police have arrested a man who is supposed to be "Jack the Ripper." He has confessed the crimes, but the cable despatch says: "The identity of the man taken into custody by the police this morning on suspicion of being the Whitechapel murderer is carefully concealed for the present by the authorities." Evidently the London police have heard of the McKinley murder inquest and are afraid their prisoner may find out that he is suspected.
