An Garda Síochána are investigating a stream of racist messages sent to former England and Arsenal striker Ian Wright.
Wright revealed on Monday afternoon that he had been subjected to vile racist abuse on social media.
An Instagram user messaged Wright with racist taunts prompting the 56-year-old to take to Twitter.
Wright wrote: "I know I'm not meant to look at them but these messages still hit me so hard man. This is a child!!!
"This kid as a direct line into me & is able to send this without any worry."
A teenager has presented himself to the gardaí for questioning in relation to the incident.
A statement from An Garda Síochnána released on Monday night read: "An Garda Síochána is investigating an incident where abusive/racist comments have been re-posted on social media platforms.
"No formal complaint has been received by An Garda Síochána at this time, but in line with An Garda Síochána Diversity and Integration Strategy An Garda Síochána commenced an investigation into the comments.
"Subsequently a male adult teenager has presented voluntarily at a Garda Station and has been interviewed in relation to this matter. A file is now being prepared for the Director of Public Prosecutions."
Show Racism the Red Card chief executive Ged Grebby earlier condemned the abuse.
Grebby said: "Ian Wright has put his head above the parapet again and I saw him on Match of the Day with Gary Lineker a few weeks ago talking about the racist abuse he suffered as a player. I'm sure he will be more than happy to report it.
"There was an Asian reporter (Sima Kotecha) yesterday for the BBC and she was abused in the middle of Leicester.
"It shows racism is society's problem and unfortunately it has been on the rise. People having been staying at home but it doesn't stop them them abusing people on social media and this is a shocking example of that."
