One of the leaders of the gang, which was intercepted by gardaí, was yesterday jailed at Limerick Circuit Court for two years and six months.
Shane Ryan Casey, aged 21, of April Rise, Old Cork Rd, Limerick, had pleaded guilty to possessing a weapon and carrying out criminal damage.
Two lesser members in the gang, brothers Jason Stokes, aged 23, Woodpark, Castleconnell, and Wesley Stokes, aged 20, Currgh Birin, Castletroy, were given suspended 18-month sentences for possessing weapons.
Another member of the gang was jailed at the same court last month for his involvement in the attempted attack.
Evidence was given at that hearing that the group organised an attack to register their anger at the social habits of women in the family.
Det Garda Ivan Muldoon gave evidence that, on October 16, 2013, gardaí received information that a group of armed men were travelling by car to the Castletroy area of Limerick.
They were on their way to the home of a family that was known to them and which had been subjected to threats over a long period and were under garda protection and surveillance.
When the car, a VW Golf, was stopped, eight men, including the Stokes brothers and Casey, were in the vehicle.
Judge Tom O’Donnell said the three were part of a posse in this escapade and fortunately, due to the quick intervention of the gardaí, no injury was caused to the family.
Since then, the family had left the country of their own volition.
The Stokes brothers, he said, were not the main protagonists and had complied with the conditions of their bail. He was prepared to take a chance with the Stokes brothers and imposed 18-month suspended sentences in respect of each.
Jailing Casey, the judge said that he had been one of the main leaders of a large group who had engaged in the maximum effort to intimidate.
