Gardaí are warning people they face fines of up to 10,000 euro and 3 years in jail if convicted of sharing photos of children at court proceedings.
It follows the high profile Ana Kriegel trial, and reports of photographs of two 14 year old boys convicted of her murder being shared online.
Gardaí have issued a statement reminding people of the anonymity of a child in court proceedings.
They say no picture which purports to be or includes a picture of the child, or which is likely to lead to his or her identification, shall be published or included in a broadcast.
Gardaí have said:
"Any person who is in contravention of the legislation shall be guilty of an offence and shall be liable—
(i) on summary conviction, to a fine not exceeding £1,500 or imprisonment for a term not exceeding 12 months or both, or
(ii) on conviction on indictment, to a fine not exceeding £10,000 or imprisonment for a term not exceeding 3 years or both."
