Gardaí were called to diffuse a situation which developed outside the offices of the Northside Regeneration Agency in Moyross in Limerick yesterday.
A crowd of around 30 people gathered to protest that their horses had been impounded.
Four horses which had been wandering in the Moyross area were impounded during an operation by Limerick City Council backed up by gardaí.
A number of horse owners gathered at the Regeneration offices to protest, even though Regeneration staff were not involved in the impounding operation.
A number of threats were made to staff.
Regeneration Chief Brendan Kenny said it was a very frightening experience for staff and they were very disappointed that staff were targeted in this way.
No arrests were made, and neither Mr Kenny nor his staff have made a complaint to gardaí
Mr Kenny says that the incident again shows the need for the rgeneration plan to get underway to bring stability to these areas.
He along with the original Regeneration plan author John Fitzgerald will be presenting their 10-year regeneration plan to Limerick city council next Tuesday.
