DASTARDLY OUTRAGE AT BALLINDERREEN
On Wednesday night, 10th inst. a startling explosion was heard in the vicinity of Ballinderreen village. At about 9.15 p.m. a loud report rang out in the direction of the schools, and at once the cry was raised that a German bomb had been thrown some few hundred paces from the village. Four policemen, including Acting-Sergt. Walsh, Kilcolgan, were quickly on the scene, but failed to discover the source of the mysterious report. In the morning, however, it was discovered that a portion of the National School wall had been blown up with gelignite, it is thought. The reason for the occurrence remains a mystery and the police are “all at sea” regarding the dastardly outrage.
