‘BOMB’ EXPLOSION IN SIDECAR
The sidecar of a motor-cycle combination, owned by the Conwy River Fishery Board, which had been left unattended near the Lledr Bridge on the Dolwyddelan-Bettws-y-Coed main road, was wrecked by a bomb explosion late on Thursday morning.
The driver of the combination, Mr Herbert Evans, of Bettws-y-Coed, a water bailiff employed by the board, escaped unhurt. He had gone up the Lledr river some distance when there was a flash followed by a loud explosion. A number of people who were near the combination at the time had a remarkable escape, and pieces of the shattered sidecar were hurled for long distances.
The Bettws-y-Coed police, who are investigating the occurrence, believe that the explosion was caused by a crudely made time-bomb, as fragments of a glass container were picked up several yards away and found embedded in the metal parts of the machine, which was also damaged. It is not yet known how the explosives became to be placed in the sidecar
