Gardaí are examining whether any of the three guns seized in Drogheda yesterday were involved in a number of recent murders.
A 38 year old man was arrested last night after the guns and ammunition were discovered during a search in the town centre.
Earlier in the day, 1.4 million euro worth of cocaine was found in the boot of a car in an industrial estate in the town and a 29-year-old man was arrested.
In a follow up search, a further 25 thousand euro worth cannabis was seized.
Gardaí in Drogheda are examining the three guns found yesterday to see if they could have been used to kill Richie Carberry in Bettystown last week or Keith Branigan in Clogherhead in August.
