Irish Prime Minister Simon Harris has said a hoax bomb threat made to his home on Wednesday night is "utterly unacceptable".
"I have young children. I have a wife," said Mr Harris.
He added the intimidation of politicians and their families cannot be allowed to continue.
Three men were arrested last week over the alleged harassment of an elected official after they gathered outside Mr Harris' home.
People are increasingly gathering outside the homes of Irish ministers, sometimes wearing masks and erecting anti-migrant banners.
Migration has become a heated debate in Ireland as the government struggles to accommodate record numbers of refugees and occasionally violent protests have been held outside accommodation centres where migrants are living.

"This is an utterly unacceptable situation," Mr Harris told reporters at a meeting of European Union leaders in Brussels on Thursday.
"Even the word "hoax" I'm not sure is a fair word, with respect, because I've no doubt these things are done to intimidate, to upset," he said.
"I do think all of us in our discourse, including [the] media, need to reflect on how we comment on these matters.
"If masked men turned up outside your house, it wouldn't be described as [a] protest," said Mr Harris.
