Justice Minister Alan Shatter has denied there is any racial profiling by the Gardaí.
Alan Shatter has given written replies to Dáil questions after suggestions that the children of traveller families were being routinely added to the PULSE computer system.
The Minister's reply says everyone is subject to the same procedures and policies in the system.
United Left Alliance TD Clare Daly, who highlighted the possibility of traveller children being added to PULSE, said the Minister's explanation could not be true.
"If what he's saying is true, then all our children are on PULSE," she said. "Interactions that traveller families would have had with gardaí would verify that rightly or wrongly, or instinctively or by order, racial profiling exists."
