Three unemployed Dublin bricklayers who were jailed earlier this month for contempt of court have been freed after giving an undertaking not to picket buildings sites operated by a construction firm.

Keith Kelly, Billy McClurg and Andrew Clarke told Ms Justice Mary Laffoy today that they would not picket sites operated by Collen Construction.

The three men were previously jailed after refusing to give such an undertaking.

Ms Justice Laffoy said the three men had learned a lesson that the court orders must be obeyed. Speaking afterwards, all three men said they would be signing on the dole on Monday.

The men had originally been brought to court earlier this month after picketing a site in Ballybrack where they had sought work. They claimed they had been refused work because of their union membership.
