Eight security guards were injured and one dog killed during a violent attack at a house in County Roscommon, following the eviction of elderly residents.

Four vehicles were burned out in the attack, which left three of the security guards requiring treatment at local hospitals and a security dog dead.

The security guards were attacked by a large group of men in hi-vis jackets wielding baseball bats at 5:30 am on Sunday at the recently repossessed house and farm at Falsk, The Irish Times reports.

“A number of people were injured during the incident, and three required hospital treatment. A number of vehicles were set on fire and a dog was also seriously injured and had to be put down as a result,” a garda spokesman said.

Three people, two of them elderly, were evicted from the home last Tuesday.

The eviction was raised in the Dáil earlier this week with Independent TD Michael Fitzmaurice alleging that gardaí “aided and abetted” a group of men from Northern Ireland in evicting the occupants.
