A Sinn Féin Senator has formally apologised to the family of Brian Stack in the Seanad following comments she made on Twitter in relation to the prison officer, who was killed by the IRA.
"I want to put on the record my most sincere apologies to the family of the late Brian Stack," Máire Devine said.
Ms Devine said she retweeted what she thought was a genuine tweet without having read the full content of the tweet.
The tweet in question used an offensive phrase to describe the former prison officer at Portlaoise Prison.
