Weapons were also seized in the operation.
The Justice Minister says the arrest of four men suspected to be part of a criminal gang in Offaly is "a matter of grave concern".
Laois-Offaly TD Charlie Flanagan says the garda operation proves normal policing is continuing, despite the increased pressure from covid-19.
Four men were arrested in Clara yesterday and weapons seized, after being intercepted by armed officers.
They're believed to be part of a 'hit squad' involved in a Traveller feud.
Minster Flanagan has been commending gardaí for their work:
