A High Court judge warned yesterday that people might be jailed if picketing persisted on Monday at a building site in Bray, Co Wicklow. He was told earlier picketing was continuing at a house-building site at Putland Road, Bray, despite injunctions granted earlier this week to the developer, Menolly Homes Ltd. A number of building workers from Bray are protesting at the site over the alleged employment of workers from Northern Ireland there while local men are unemployed.
