It's believed two children missing from Northern Ireland could be in the Republic.
The PSNI is growing more concerned about the welfare of the brothers from north Belfast.
Five year-old Patrick Hovarth and his older brother, Fabricio who's 8 were seen getting into a black Ford car around 6 o'clock on Friday evening in the Limestone road area of Belfast.
Police in the North are appealing to the public for help in finding them - both boys are dark-haired.
Younger brother, Patrick, was wearing light-coloured bottoms and a top with black shoes. Fabricio was wearing grey bottoms and a purple and green top.
The PSNI believes they may be in the company of a relative in the North or possible in the Republic, particularly in Dublin.
They're appealing to that person to get in touch with police as soon as possible.
They're also urging members of the public who have any information about the boys or have seen them since Friday evening to contact police immediately.
