Murderous attack on a new Policeman.

Sunday evening a most serious riot took place in Peter-street, Berwick-street, Soho, which is solely inhabited by the lowest Irish. A fight occurred nearly opposite the house of Reuben Marten, the pugilist (the City of London public-house), when a policeman named David Sims, section C, No.192, interposed to stop it, and one of the combatants he seized, intending to take him to the station-house in Vine-street, Piccadilly, when a large body of Irish, consisting of men and women, rushed forward to the rescue of their countryman, which they very soon effected. One of the party, a robust fellow, struck the officer such as a tremendous blow, that he fell to the ground as if struck with a pistol - ball. The ruffians, whilst the man lay prostrate on the ground bleeding profusely, took the truncheon from his pocket, with which he belaboured the man's head with such violence that his scull was severely fractured; and whilst he was thus engaged, the rest of the party kicked and jumped upon him. Information was instantly sent to the station-house, when Inspector Rates and a party of men hastened to the scene; but by the time they arrived the party had dispersed, and the wounded man had been carried to the house of Messrs. T. Dixon and Butvine, the surgeons, on a shutter, when it was found that nearly all his ribs were broken, and that he was in a dying state. He was instantly carried to the hospital.
