A man has been arrested in connection with an investigation into criminal damage and an assault at a repossessed house in Strokestown, Co Roscommon.
Eight security men were injured and six vehicles were burnt out in the incident at the property on December 16th last year.
The attack came after security guards were filmed evicting a family from the house a number of days before.
A 50-year-old man was arrested in Roscommon this morning.
He is being held at Castlerea Garda Station under Section 30 of the Offences Against the State Act, 1939.
He's the sixth person to be arrested in connection with the investigation.
