Gardai are investigating a complaint of statutory rape against a prominent sports journalist.
He is alleged to have had sex with an under-age girl, which by law amounts to statutory rape.
The victim is in her mid-teens and has been interviewed by gardai about the complaint.
The incident is alleged to have taken place in Dublin.
Relatives of the girl are understood to have lodged the complaint with the gardai in recent weeks.
Detectives have not yet interviewed the journalist about the allegations, but are expected to meet him in the near future.
A garda investigation was launched two weeks ago after the writer's child allegedly discovered text messages he had sent to the girl on an old mobile phone.
It is understood the child found the texts while putting a new sim card into the phone.
The journalist had given the phone to the child, who was collecting them to donate to a charity.
It is understood she showed the messages to other family members. They then handed the phone over to gardai.
It is alleged the journalist tried to take his own life. He is now receiving medical care.
