Gardaí have charged three men arrested in Athlone as part of an investigation into a number of threats to kill and cause serious harm made on social media.
The men, one aged in his 40s and two in their 20s, are expected to appear before Mullingar District Court tomorrow.
The arrests were made after a 13-year-old girl was seriously injured in a machete attack in Co Fermanagh.
The girl remains in hospital in Enniskillen after the attack at her home in Lisnaskea on Saturday night.
She required more than 300 stitches after being cut several times with a machete.
A 41-year-old woman also received hospital treatment for cuts to her arms and legs.
Those who carried out the attack recorded it and posted footage on social media.
PSNI detectives investigating the incident are liaising with gardaí in Athlone.
Gardaí say they conducted a series of planned searches in the Athlone area and seized a number of devices and weapons.
