A man has been arrested in connection with online threats against Taoiseach Simon Harris. 

Gardaí investigating online threats against the Taoiseach made the arrest this morning. 

The man, aged in his 40s, is being questioned at a Garda Station in the northwest.

It is understood the online threats against Mr Harris and his family remained online for at least two days after Gardaí asked Instagram owner Meta to remove them.

Separately, Gardaí are also investigating several other threats against Mr Harris since he became Taoiseach.

A man was arrested on Friday in connection with a bomb threat on Mr Harris' home. 

He has since been released and file is being prepared for the Director of Public Prosecutions.

The threat was made through a call to the Samaritans helpline at around 6pm on Wednesday, June 26th. 

The caller provided a code word which led to Gardaí immediately carrying out searches at the property. 

No devices were found. 

Meanwhile, masked men gathered outside his home on two separate occasions earlier this summer, protesting Ireland’s immigration policy.

Gardaí are understood to be concerned about the threats – and have advised the Taoiseach to move his family to Farmleigh House in the Phoenix Park.

It is understood they believe the residence, which was purchased by the State in 1999 is easier to protect.

On Tuesday, the Taoiseach said he would not be “deterred from doing my job”.

“There can be no hiding place for anyone seeking to threaten, attack or harm people or to incite others to do so,” he said.

“Politicians have become a regular target, and it is on the brink of being viewed as acceptable or a normal part of the job.

“It is not acceptable. I get up every day and go to work and work as hard as I can - so do most politicians I know from all parties and none."

Mr Harris also praised An Garda Síochána making “us proud every day in their work” and thanked the Irish people “for their kindness and decency - it means the world to me and my family.”
