The security alert at the Wattlebridge Road area, County Fermanagh has now been concluded.
South Area Commander, Chief Superintendent Andy Freeburn said: “I can confirm that the security alert has now ended and all roads have reopened. I would like to thank the local community for their patience and support.
"This was a challenging and complex operation, made all the more difficult by the weather conditions. I would also like to thank our officers, our colleagues in An Garda Síochána and army bomb disposal experts for their assistance and expertise.
"A device left at a bus shelter has been declared a hoax. Four rounds of ammunition have also been recovered. They have now been taken away for forensic examination.
"At this stage, it is too early to determine if any weapons were fired, as has been claimed.
"No community should have to live under the threat of such violence and we will now focus upon our investigation.
"We would ask anyone who saw anything suspicious in the area from January 13th to get in contact with us on 101.”
