Gardai are investigating an incident of false imprisonment in Claremorris on Sunday evening.
Four men were arrested in Co Roscommon later that evening - including a man in his mid-30's, one in his early 40's, one in his late teens and a juvenile in his late teens.
They were detained at Castlerea Garda Station in connection with the incident.
All four individuals have since been released without charge.
A file will now be prepared for the Director of Public Prosecutions.
