Sinn Fein candidate Mickey Brady has said he will "not be deterred" by a third death threat in 24 hours.
On Monday Mr Brady was told by the PSNI a threat had been made against his life.
He was then told a second threat had been received in a phone call in the early hours of Tuesday morning.
This morning there was a bomb threat at his family home.
On Monday the Newry and Armagh runner was informed of a threat just 24 hours after Deputy First Minister Martin McGuinness's home in Londonderry was attacked.
He said: "These threats come on the heels of threats made against my party colleague Conor Murphy and the cowardly attack carried out by criminal elements on local republican Frank McCabe Junior, who was badly injured in a bomb attack near his home in Cullyhanna in February.
"Those responsible for this latest threat obviously did not get the message that I will not be deterred from working for the community and carrying out my duties as a Sinn Féin representative.
“Sinn Fein will not be intimidated.
"I have been heartened by the support I have received from across the constituency and will continue to campaign to retain the Newry and Armagh seat for Sinn Féin and represent everyone equally."
Ulster Unionist MLA Danny Kennedy condemned the death threat that was issued against Sinn Fein’s Mickey Brady, as an attack on democracy.
Mr Kennedy, who is his Party’s Westminster candidate for Newry & Armagh, said: “I unreservedly condemn this threat against Mickey Brady, as I would condemn any threat against anyone.”
Mr Brady emphasised that he will not be intimidated.
"I will not be intimidated by this threat from continuing to campaign to retain the Newry Armagh Westminster seat for my party.
"I have worked hard as an MLA to represent all the people of Newry/Armagh without fear or favour.
"Whoever is behind this threat needs to realise that I will not be deterred from carrying out my duties on behalf of all my constituents or my party."
Mr Brady is running for Sinn Fein to win the Newry and Armagh seat, which has been held by his party colleague Conor Murphy since 2005.
He is the front-runner ahead of agreed unionist Danny Kennedy and SDLP's Justin McNulty.
