Gardaí in Athlone are investigating a number of threats "to kill and cause serious harm to persons" made on social media over the past few days and say it may be linked to an attempted murder in Fermanagh on Sunday.

In a statement, a spokesman said: "This morning Athlone Gardaí conducted a number of planned searches in the Athlone area, searching for weapons which were displayed in these videos and media devices used in the commission of these crimes. A number of electronic devices and weapons were seized during the searches.

"These involved Garda resources from Athlone and the Regional Support Unit. During the course of these searched three males from the Athlone area were arrested. One male is in his late 40s and the other two males are in their 20s. These males are currently being detained at Mullingar and Athlone Garda Station and are detained under Section 4 of the Criminal Justice Act 1984."

The statement added: "Gardaí in Athlone are liaising with the PSNI in relation to the persons arrested and the social media videos as may be connected to a recent serious incident in County Fermanagh, which is under investigation by the PSNI".

It's understood the incident referred to was the attempted murder of a 13-year-old girl in a house in Lisnaskea on Sunday.
