On Monday evening while Mr. Sean McKenna, superintendent of the Prudential Insurance Co., and late brigade police officer at Naas, with Mr. Muldowney, were walking from Kildare station towards the town a shot was heard, evidentially either fired or accidentally discharged by some men walking behind them. Mr. McKenna turned round to the men and enquired what was wrong. He was informed by the men, seven in number, that they had been sent after him and his companion in the belief that they were C.I.D. men. They were questioned by the men, who were armed with revolvers and hand grenades, and having established their identity were allowed to go. The hold-up occurred near the railway hotel shortly after noon.
