H.A. BYWORTH & Co.
32 & 34, Clerkenwell Road, later, 19 & 21, Heddon Street, Regent Street, London
The bold coup of the jewel gang in cleaning up on the premises of H. A. Byworth & Co., the Heddon St. diamond mounters and dealers in precious stones has caused no little consternation to the jewelry trade here. The very audacity of the theft has demonstrated to the jewelers and to Scotland Yard the sort of versatile organization this jewel gang really is. Messrs. Byworth estimate their loss at £100,000 and a reward of £10,000 has been offered for information leading to the apprehension of the thieves. The plans for the robbery were well laid and the members of the gang who carried out the theft well versed in science. The basement of the jewelry premises was cleaned out over night previous to handing over to new tenants. Members of the gang, it is thought, secreted themselves. A powerful oxyacetylene flame was used to eat a way through the great safes. Three heavy cylinders of oxy-acetylene wrapped in linoleum were left on the premises by the gang. Rolls of linen and canvas had been used to erect a screen in order to shield the flame from the cylinders. A quantity of rubber piping also was discarded. Canvas water buckets were used and sand was scattered under the safes to prevent the molten metal setting fire to the floor. The work of burning open the first safe occupied several hours. Inside two keys were found which opened a large Ratner safe in an adjoining workroom stored with gold, platinum and uncut diamonds. The safe containing the precious stones was divided off into little drawers each of which contained stones mounted in wax and upon which the jewelers were working. These included diamonds, emeralds, sapphires and pearls. The thieves took the immense trouble of extracting each stone from its wax setting. Scotland Yard has taken over the wax settings and hopes to get finger print clews from them. A third safe was untouched. Large quantities of platinum in sheet-plate form and unfinished gold were taken. In fact, so much raw material was carried away that the 50 skilled jewelry experts employed by the firm are out of work until new supplies can be obtained. Scotland Yard is looking for the motor lorry that carried the oxy-acetylene cylinders and the cement and linoleum and wood used for the canvas frame and a net has been flung over all garages within a radius of 12 miles from the robbery.
